Core Responsibilities
Design, Implement, and Maintain Network Infrastructure: Plan and configure LAN/WAN networks, switches, routers, wireless access points, and VPN connections to meet business needs. This includes setting up routers, switches, firewalls, and VPNs for offices and remote users, and upgrading network hardware or cabling as the company grows.
Monitor Network Performance and Troubleshoot Issues: Continuously monitor network activity and performance, identify connectivity problems or bottlenecks, and swiftly resolve network outages to ensure high availability and optimal speed. This involves using network monitoring tools, analyzing alerts or logs, and proactively addressing latency or bandwidth issues before they impact users.
Network Security and Access Control: Implement and manage network security measures, including configuring firewalls, intrusion prevention systems, secure Wi-Fi, and VPN access policies. Ensure only authorized users/devices connect to the network and that data is protected through encryption and up-to-date security protocols. Protect against cyber threats by applying security updates, monitoring for unusual traffic, and enforcing compliance with security policies.
User Support and Collaboration: Work closely with system users and the IT helpdesk to resolve connectivity problems and network access issues in a timely manner. Provide friendly technical support for network-related requests (e.g. a user cant connect to Wi-Fi or VPN), and liaise with other teams (systems, cloud, or support teams) to troubleshoot and fix cross-domain issues. Coordinate with vendors or service providers (ISP, cloud services) when external support or escalation is needed.
Documentation and Network Administration: Maintain up-to-date documentation of network configurations, IP address assignments, diagrams, and change logs. Follow change management processes when making network changes (e.g. recording configuration changes, firmware updates). Create and update network topology diagrams, standard operating procedures,
and user guides (for example, VPN setup instructions) as needed to ensure knowledge is shared and audits can be passed.
Disaster Recovery and Maintenance: Perform regular data and configuration backups for critical network devices and implement disaster recovery procedures. Schedule routine maintenance and upgrades (e.g. applying patches, renewing certificates, replacing faulty hardware) during appropriate maintenance windows to minimize disruption. Test failover mechanisms and backup links (if available) to ensure high-availability network design for critical systems.
Stay Current and Continuous Improvement: Keep abreast of new networking technologies, cloud integration methods, and best practices relevant to SMB environments. Attend training or workshops to continuously improve skills. Proactively recommend and implement network improvements or optimizations (such as refining Wi-Fi coverage, segmenting traffic with VLANs, or adopting better monitoring tools) to enhance performance, security, and scalability of the network.
Must-Have Skills
Hard Skills
Networking Fundamentals: Strong understanding of TCP/IP networking, subnetting, routing and switching concepts, VLANs, and common protocols like DNS and DHCP. Should be able to configure and troubleshoot IP addressing issues, DHCP assignments, name resolution problems, and basic routing for an SMB network.
Network Hardware & Architecture: Hands-on experience configuring routers, switches, and wireless APs, ideally from mainstream vendors (e.g., Cisco, HP/Aruba, Ubiquiti). Familiarity with firewall appliances or UTM devices for SMB (such as Cisco ASA/Meraki, Fortinet, or SonicWall) and understanding of how to set up site-to-site and client VPNs. Able to interpret network diagrams and deploy network gear in a structured way.
Network Security Practices: Solid knowledge of network security principles and tools for example, able to configure firewall rules, VPN access, VLAN segmentation, and wireless security (WPA2/3). Understands how to apply updates/patches, manage user access control, and implement secure protocols to protect data in transit. Basic awareness of intrusion detection/ prevention and common threats (phishing, malware traffic) to quickly respond to security incidents.
Troubleshooting & Tools: Proficiency with network troubleshooting tools and methodologies. Can use utilities like ping, traceroute, and nslookup to diagnose issues, and analyze packet captures with Wireshark or similar tools. Experience with network monitoring software (e.g., SolarWinds, PRTG, Nagios) to track performance and outages. Able to systematically isolate problems (layer-bylayer troubleshooting of OSI model) and resolve them under time pressure.
Cloud & Hybrid Networking: Familiarity with integrating on-premise networks with cloud services. For example, knowledge of Azure or AWS networking basics (virtual networks, VPN gateways) to support an Office 365 or cloud-hybrid environment. Understands how services like Microsoft 365 or Google Workspace tie into network considerations (such as ensuring DNS, firewall, and identity (Azure AD/Google) configurations allow smooth access for users)
Automation/Scripting (Nice-to-have): Ability to automate routine tasks or configurations using scripts or tools (PowerShell, Python, or Ansible). While not a primary duty in SMB, scripting skills are a plus for efficiency e.g., automating network device backups or bulk updates. This reflects a modern mindset to reduce manual repetitive work (as network automation skills are increasingly in demand)
Soft Skills
Analytical Problem-Solving: Strong troubleshooting and analytical thinking skills to diagnose complex networking issues. Able to break down problems, find root causes, and devise effective solutions calmly. This includes a dose of creativity and persistence when facing unfamiliar issues, ensuring minimal downtime.
Communication Skills: Excellent ability to communicate technical information to non-technical staff in clear, simple terms. Can listen to user concerns, ask probing questions, and explain solutions or preventive measures without jargon. Also capable of writing clear documentation and status reports (e.g., incident reports, user advisories). Effective communication is considered a secret weapon for network engineers to influence and collaborate
Teamwork and Interpersonal Skills: Works well in cross-functional teams and can collaborate with colleagues in IT support, software, or operations. Strong teamwork skills willing to assist others, share knowledge, and coordinate tasks to achieve bigger IT goals. Builds positive relationships with coworkers and vendors, and demonstrates empathy and patience when dealing with end-users frustrations.
Time Management: Able to juggle multiple tasks and prioritize effectively, especially when dealing with concurrent issues or projects. For example, can balance an urgent outage with routine maintenance duties by triaging impact. Meets project deadlines for network upgrades or deployments through careful planning and scheduling, which is vital in a resource-constrained SMB environment.
Attitude and Work Ethic:
Detail-Oriented and Thorough: Diligence in attention to detail is essential small misconfigurations can cause big problems. A good network admin double-checks IP addresses, cable placements, and configuration changes. This reduces errors and avoids rework or downtime Being detail-oriented ensures IT infrastructure is set up correctly the first time, without needing frequent troubleshooting for avoidable mistakes
Reliability and Responsibility: A dependable professional who takes ownership of the networks uptime and security. Reliability and responsibility are top traits valued by hiring managers for engineering roles. This means the engineer can be counted on to respond to incidents (even occasionally after hours), follow through on tasks, and uphold IT policies without needing constant supervision.
Proactive & Self-Motivated: Shows initiative in identifying potential network improvements or looming issues before they escalate. For instance, proactively monitoring capacity and recommending an upgrade or noticing a security gap and patching it. A self-motivated learner who keeps skills updated (e.g., pursuing relevant certifications or training) and stays current with evolving tech. Willingness to attend training and adapt to new technologies is expected.
Calm Under Pressure: Maintains composure and clear thinking during network crises or high-pressure situations (like a major outage). Can manage stress effectively so as to troubleshoot systematically rather than panic. This trait ensures attention to detail even when under pressure, which is vital to resolve issues correctly
Customer-Service Orientation: Understands that IT is a service to the business demonstrates a helpful, patient attitude when supporting end-users. Focuses on resolving user problems and improving their experience, not just the technical fix. This positive attitude builds trust with non-IT staff and reinforces the IT teams reputation for being approachable and solutions-oriented.
Tools & Systems
Systems / Artifacts
Technologies and Tools commonly used: This mid-level role works with a variety of mainstream IT tools and systems typical in SMB environments:
Productivity & Collaboration Suites: Experience administering Microsoft 365 or Google Workspace environments is important, as most SMBs rely on one of these suites for email, calendaring, file sharing, and user management. For example, managing Exchange Online settings (M365) or Gmail/Google Admin console (Workspace), handling user accounts, groups, and permissions, and ensuring integration of these cloud services with on-premises networks (such as configuring DNS records for email, or single sign-on integrations).
Network Infrastructure Equipment: Hands-on with business-grade network hardware:
Routers (for connecting to ISPs and linking sites),
Switches (managed switches for VLANs and traffic management),
Wireless Access Points (enterprise Wi-Fi systems for office coverage),
Firewalls/Gateways (for Internet edge security and VPN). Common brands in SMBs include Cisco (and Meraki for cloud-managed networks), Juniper, Ubiquiti UniFi, HPE/Aruba, MikroTik, or SonicWall/Fortinet for firewalls. The engineer should be comfortable with web-based management GUIs and command-line interfaces (CLI) for these devices.
Operating Systems & Servers: Familiarity with Windows Server roles (Active Directory, DNS, DHCP) or Linux servers that might be part of the network environment. For instance, an SMB may use Active Directory for central authentication; the network admin may not be the primary AD admin but needs to understand how network policies (DNS, DHCP, NPS for RADIUS, etc.) tie in. Knowledge of NAS/SAN or file servers and how they connect to the network is also useful.
Cloud and Remote Access Systems: Knowledge of VPN platforms (e.g., IPsec site-to-site VPNs configured on firewalls, OpenVPN or Azure AD Application Proxy for remote access) to support hybrid work. Understanding how to ensure fast, secure access to cloud resources is key as many SMBs keep some services on-premises while moving others to cloud. Tools might include Azure VPN Gateway, Cisco AnyConnect, or even remote desktop gateway solutions.
Network Monitoring and Management: Use of monitoring tools to oversee network health and respond to issues. Examples: SolarWinds or PRTG for monitoring device uptime and performance, Wireshark for packet analysis, and built-in utilities (ping, traceroute, ipconfig/ifconfig) for quick diagnostics. Also, use of network configuration backup tools or logging systems that track changes on network devices.
IT Service Management (ITSM) & Documentation: Working with a ticketing system or helpdesk software (such as Jira Service Management, ServiceNow, Freshservice, or even simpler ones like Spiceworks) to track user issues and changes. Maintaining a knowledge base or document repository (e.g., Confluence, SharePoint, or even a shared OneNote/Google Docs) where network artifacts are stored: network diagrams, IP address inventories, device configuration files, vendor contacts, and standard operating procedures.
What to Assess
Assessment Tasks
/Attention to Detail: ~10% High weight because catching errors is critical. A strong candidate should ideally get these entirely correct. Even one missed detail could be weighed heavily.
Interview Performance 50% of total score. Within interview:
Behavioral (teamwork, conflict resolution): ~15% Did they demonstrate the desired behaviors (collaboration, communication)
Technical Depth: ~20% Based on the two technical questions; are their answers correct and insightful We rate each technical answer on correctness and completeness (e.g., scale 1-5). Critical mistakes here (like not knowing a fundamental concept during interview) could be a pass/fail trigger.
Situational (on-the-spot thinking under pressure): ~10% How well did they handle the scenario question (CEO complaint) We look for calm, structured approach.
Attitude/Cultural Fit: ~5% From the attitude question and general demeanor. If they show a clear passion for learning and a positive attitude, full points; if not, low points. Any big cultural red flag (arrogance, negativity) can be a pass/fail trigger regardless of score.
Time: ~8 minutes
This section tests specific networking knowledge expected at mid-level. It includes direct questions about technology and configuration.
Q1. What does the DNS service do in a network (Open-ended, one or two sentence answer)
-Expected Answer: It translates human-readable domain names into IP addresses (and vice versa) to route traffic to the correct host on a network or the internet. For example, DNS will resolve a name like
www.example.com to its numerical IP address so your computer can connect to the right server. -Grading Key: Full credit if the answer mentions convert/resolve domain names to IP addresses (or equivalent phrasing). Additional mention of reverse (IP to name) is fine but not required. Answers that describe it incorrectly (e.g., DNS secures the network or DNS is a database without mentioning names to IPs) get no credit. This is a fundamental concept; the expected answer is straightforward.
Q2. Which TCP/IP layer protocol would you use for securely transferring files between two systems, and what port does it typically use
a.
FTP, Port 21
b.
HTTPS, Port 443
c.
SFTP (SSH File Transfer Protocol), Port 22
d.
HTTP, Port 80 -Correct Answer: c. SFTP, Port 22. -Grading Key: The question asks for a secure file transfer protocol. SFTP (which runs over SSH) is secure and typically uses TCP port 22. Answer (a) FTP is not secure (unencrypted). (b) HTTPS is secure but its for web traffic, not specifically file transfer between systems. (d) HTTP is not secure and not for files specifically. Full credit for (c). No partial credit; only one correct option.
Q3. You have a network printer that needs a static IP address. Briefly list the steps to configure this printer with a static IP on a typical small business network. (Open-ended answer expected, 2-3 key steps)
-Expected Answer: For example: 1) Access the printers network settings via its control panel or web interface. 2) Assign an IP address outside or reserved from the DHCP range (to avoid conflicts) that is in the correct subnet, along with the correct subnet mask and the networks gateway IP. 3) Enter the DNS server addresses if required. 4) Save/apply the settings and possibly update any DHCP reservations or documentation to note this static assignment. -Grading Key: Full credit if the answer mentions choosing an appropriate IP in the network and configuring the printer with that IP, mask, gateway. Specifically, looking for mention of within the correct subnet and not conflicting with DHCP. Also mentioning updating settings on the printer itself. Partial credit (e.g., half) if they say set a static IP without noting avoiding DHCP range or setting gateway. No credit if they describe something unrelated (like setting it via DHCP reservation but not answering question directly though DHCP reservation is actually an acceptable approach too, credit if mentioned). The key is understanding how to place a static IP properly.
Q4. Multiple Choice: Which statement about VLANs is true
a.
VLANs allow you to segment a network logically without needing separate physical switches.
b.
VLANs automatically encrypt all traffic within them.
c.
All VLANs on a switch share the same broadcast domain.
d.
Devices on different VLANs can communicate freely without a router. -Correct Answer: a. VLANs allow logical network segmentation without separate physical switches. -Grading Key: (a) is the definition of VLANs. (b) is false (VLANs are not encryption). (c) is false (each VLAN has its own broadcast domain). (d) is false (inter-VLAN traffic requires a router or Layer3 device). Full credit for (a) only.
Section 2 Scoring: Each question in hard skills is equally weighted (for example, 1 or 2 points each). A strong candidate should score high here (missing at most one minor detail). Fail criterion: If a candidate fails to answer Q1 (DNS) correctly, thats a big concern. Also, multiple misses in this section may indicate insufficient technical knowledge.
Section 3: Situational Judgment (SJT) Time: ~6 minutes
This section presents workplace scenarios to assess the candidates judgment in handling them. Each scenario has one best answer aligned with company best practices and one or more clearly poor answers.
Scenario 1: You made a network configuration change that accidentally caused an hour of downtime for the company website during business hours. What do you do next
a.
Quietly revert the change and hope no one notices to avoid blame.
b.
Immediately revert the change, then notify your manager and the team about the incident and impact, taking responsibility and explaining how you will prevent this in the future.
c.
Blame the outage on a software glitch unrelated to your change, since its already fixed.
d.
Leave the change in place and fix it after hours, since the site is already down anyway. -Correct Answer: b. Revert the change and promptly inform management/team, taking responsibility and planning prevention. -Grading Key: (b) demonstrates honesty, responsibility, and prompt communication the ideal judgment in an SMB culture that values transparency. (a) and (c) are ethical red flags (hiding the truth, failing integrity)
those should score 0. (d) shows poor judgment by extending downtime unnecessarily. Full credit only for (b). This tests integrity and accountability.
Scenario 2: A department head asks you to urgently give an outside contractor access to the company Wi-Fi and internal file server. The proper process is to create a guest Wi-Fi account and limited VPN access, but that takes time and the department head is pressuring you to just share the main Wi-Fi password. How do you respond
a.
Give the contractor the main office Wi-Fi password to keep the department head happy you can always change it later.
b.
Explain the security policy and offer to quickly set up a guest Wi-Fi login or temporary account that complies with policy, even if it takes a little extra time.
c.
Tell the department head its against policy and refuse without explanation.
d.
Ask the contractor to use a personal hotspot instead, to avoid the hassle. -Correct Answer: b. Follow security policy by providing an alternative (guest network or proper account) and communicate this to the department head. -Grading Key: (b) is correct as it balances security with helpfulness. (a) is a serious security breach zero points. (c) is rigid and doesnt solve the problem (poor customer service, though it upholds policy, it lacks communication of a solution) partial credit at best if any. (d) avoids addressing the need and is not practical for long-term no credit. Full credit for (b). The best answer shows both adherence to rules and willingness to help an important judgment skill.
Scenario 3: You notice that a fellow IT administrator occasionally bypasses change control and makes network changes directly, which could be risky. What do you do
a.
Ignore it; they are experienced and probably know what theyre doing.
b.
Privately discuss with the colleague, expressing your concerns about the practice and the risks involved, and suggest following proper change control. If it continues or is serious, escalate to your manager.
c.
Immediately report the colleague to upper management without discussing it with them.
d.
Publicly call them out in the next team meeting so everyone is aware. -Correct Answer: b. Talk to the colleague privately to address the issue constructively; escalate only if needed. -Grading Key: (b) shows professionalism, teamwork, and concern for process. (a) ignoring is wrong no credit. (c) jumping straight to reporting may be too harsh without giving the colleague a chance, unless the risk was extremely high (c) gets less credit than (b). (d) public shaming is a poor approach zero. Full credit for (b); some partial for (c) if justified, but ideal answer is (b). This gauges interpersonal judgment and adherence to process.
Section 3 Scoring: Each scenario is typically one question (e.g., 3 scenarios = 3 questions). Full points for choosing the best action. The AI scoring checks if the correct option (the one aligned with company values/ policies) was selected. Selecting blatantly wrong ones (especially unethical choices) could be marked as automatic fail flags.

Scoring Guidance
Scoring Weights: The hiring process consists of the 30-minute test and the 30-minute interview. We will combine these, but weight them to ensure a holistic evaluation:
Online Assessment (Test) 50% of total score. Within this test:
Cognitive Ability: ~10% (of total) A decent score here indicates problem-solving; not the highest weight but important.
Hard Technical Skills: ~15% These are core competencies; a failing score here (<70% in this section) is typically disqualifying.
Situational Judgment (SJT): ~10% Ensures ethical and good judgment; any critical mistake (choosing a clearly unethical option) can trigger disqualification despite score.
Red Flags
Disqualifiers
When evaluating candidates for this Network Engineer/Administrator role, certain behaviors or indications can be red flags that suggest a poor fit or lack of readiness. The following are significant red flags or disqualifiers to watch out for:
Poor Fundamental Knowledge: Inability to answer basic networking questions or misuse of common terms (e.g., confusing IP addressing or not knowing what DNS does) is a major red flag. A mid-level engineer should have solid fundamentals if they cannot explain simple concepts like DHCP or subnetting, it indicates a skill gap.
Negligent Attitude Toward Security/Policy: Downplaying the importance of security best practices or showing willingness to cut corners (like disabling firewalls, ignoring update schedules) to get quick results. For example, if a candidate says they would share their credentials or turn off security features to appease a user, thats disqualifying.
Lack of Attention to Detail: Multiple instances of carelessness, such as making spelling errors in configurations in a test, or not noticing critical information in a scenario. Since network admin work demands precision, any sign of sloppiness e.g., misreading a scenario and giving an unrelated answer, or configuring an IP incorrectly and not catching it is concerning.
Poor Communication or Arrogance: If the candidate communicates in a condescending or extremely terse manner to non-technical prompts (for instance, blaming users for problems in the communication task, or using excessive jargon despite prompts to simplify), its a red flag. A network engineer who cannot communicate respectfully and clearly will struggle in a collaborative SMB setting. Dismissing end-user perspectives or bragging without listening are signs of poor teamwork attitude.
Inability to Troubleshoot Systematically: When walking through troubleshooting scenarios, a red flag is jumping to conclusions without gathering facts, or randomly trying fixes without logic. For example, if asked how to troubleshoot an outage, a candidate who says Id immediately replace the router without checking simpler causes first shows a lack of structured approach. Mid-level
engineers should demonstrate systematic problem-solving; a disorganized approach is disqualifying for a role that requires methodical thinking.
No Questions or Curiosity: A candidate who asks zero questions about the environment or assumes they know everything can be a red flag. Networking roles often require clarifying requirements and understanding context. If they dont show any curiosity (for instance, not asking about what tools are used, or specifics of the network setup), it might indicate low engagement or poor analytical thinking.
Overemphasis on One Skill, Ignoring Others: For example, a candidate who only talks about their Cisco certification and configuration prowess but fails to mention any teamwork, documentation, or user support experience could be a bad fit. An SMB Network Engineer needs to wear multiple hats. Red flag if someone says I only do networking, I dont like dealing with users or documentation this silo mentality doesnt fit the role.
Dishonesty or Evasion: Any sign of dishonesty (claiming experience that doesnt check out) or evading direct questions. In an interview, if the candidate cannot provide concrete examples for claimed experience, or gives answers that are suspect (like buzzword-filled responses with no depth), thats disqualifying. Trustworthiness is crucial since this person handles critical network systems.
Failure in Accuracy Tests: On the practical assessment, if the candidate misses critical errors in the deterministic tasks (like not noticing the wrong subnet in an IP config, or failing to spot a glaring log error), its a red flag. It suggests they might make or overlook similar mistakes on the job, which could lead to downtime or security incidents.
Negative Attitude or Cultural Mismatch: Signs of a poor attitude, such as speaking ill of past colleagues/employers, not taking responsibility for past mistakes, or exhibiting a know-it-all demeanor. An SMB environment needs team players who are adaptable. If the candidate seems inflexible (e.g., unwilling to learn new tools because Ive always done it this way), that could be a disqualifier as well.
Any one of these red flags would warrant careful consideration; multiple red flags would likely disqualify a candidate outright. The goal is to find someone technically competent and aligned with the companys collaborative, detail-oriented culture absence of these red flags helps indicate that fit.
10. Assessment Blueprint (30-Minute Test)
Overview: The assessment is a 30-minute test divided into 5 sections targeting different competency areas: cognitive ability, hard skills, situational judgment, soft skills, and attention to detail. The test uses a mix of multiple-choice and short-answer questions. Each question has a definitive correct answer or grading rubric, enabling AI-driven scoring. The sections and sample questions (with answers and grading keys) are as follows:
Section 1: Cognitive Ability (Problem-Solving) Time: ~5 minutes
This section assesses the candidates logical reasoning and problem-solving in a networking context, ensuring they can deduce causes from symptoms.
Q1. You can ping a servers IP address successfully, but you cannot reach the application on that server via its domain name. What is the most likely cause of this issue
a.
The server is down.
b.
The network is experiencing high latency.
c.
There is a DNS configuration problem.
d.
The firewall is blocking all traffic. -Correct Answer: c. There is a DNS configuration problem. -Grading Key: The only correct choice is (c). Rationale: If ping by IP works but the domain name doesnt resolve or connect, its typically a DNS issue. Full points for selecting (c). Options (a), (b), (d) are incorrect (server isnt down if ping works; latency wouldnt prevent name resolution; firewall blocking all traffic would also block ping). No partial credit since this is single-choice.
Q2. A network has the IP address range 10.0.0.0/24. Approximately how many usable host addresses are available in this subnet (Open-ended numeric answer)
-Expected Answer: 254 usable host addresses. -Grading Key: The correct calculation is that a /24 has 2^8 = 256 addresses, minus 2 reserved (network and broadcast) = 254 usable hosts. Answers between 250254 with explanation get full credit (254 is the exact). If a candidate answers 256 or 254 without context, auto-scoring will accept 254 only. (Partial credit: If they answered 256 misunderstanding usable count, thats essentially wrong, so likely no credit here as its a straightforward knowledge point.)
Q3. Which of the following is not a network routing protocol
a.
OSPF
b.
BGP
c.
EIGRP
d.
SMTP -Correct Answer: d. SMTP -Grading Key: SMTP is an email protocol, not a routing protocol; OSPF, BGP, EIGRP are all routing protocols. Full points for (d). No partial credit; this is a direct knowledge question.
Section 1 Scoring: Each question is worth equal points (1 point each for example). A candidate should ideally get all correct, but a strong candidate might miss at most one. Getting Q1 correct is crucial as it tests applied reasoning (pass/fail trigger if Q1 is missed maybe, since its fundamental reasoning with DNS).
