IT support interview questions: 23 questions and a scorecard for interviewers
The short answer
Good IT support interview questions test how a candidate troubleshoots, prioritizes tickets, communicates with frustrated or non-technical users, protects accounts and data, documents fixes and knows when to escalate. Ask for real examples, such as a problem they solved that others had given up on or a busy morning on the help desk, and listen for a clear method and how they kept the user informed. A recruiter screen before the client’s technical round should confirm the systems they have supported, any certifications the client requires, shift pattern, right to work, start date and pay expectations. Score every candidate against the same five criteria so the decision rests on evidence.

When to use these questions
IT support specialists keep people working, whether on a help desk, a service desk or on-site, so an interview needs to show how someone diagnoses a problem methodically and how they treat the user while they do it, not only which tools they have heard of. The strongest evidence comes from specific tickets and incidents, described step by step, including what they wrote down afterwards.
For agency recruiters, the screen before the client’s technical round is where to confirm the essentials: the operating systems, devices, directory and ticketing tools the candidate has supported, the support tier the client needs, certifications such as CompTIA A+ if the client asks for them, and the practical facts of shifts, on-site work, start date and pay expectations. Communication and service attitude can be judged directly in the screen, even by a recruiter without an IT background.
23 IT support interview questions
Grouped by what they test. Pick the questions that match the role, ask every candidate the same ones in the same order, and score each answer against the scorecard below.
Troubleshooting method
Ask about real tickets. A good support specialist narrows a problem down step by step instead of trying fixes at random.
Question 1: A user calls the help desk and says “the internet is down.” Walk me through what you check, in order.
- Why ask it:
- Tests a structured troubleshooting method on a common, vague report.
- A strong answer shows:
- Scoping the problem first, such as one user or many and wired or Wi-Fi, then working through the device, network settings, connectivity and services in a logical order.
- Follow-up:
- What changes if three more people report the same thing in the next five minutes?
Question 2: Tell me about a problem you solved that other people had given up on. How did you find the cause?
- Why ask it:
- Shows persistence and a methodical approach.
- A strong answer shows:
- Gathering details, reproducing the issue, changing one thing at a time and confirming the fix with the user.
Question 3: A user’s laptop has been very slow since yesterday. What do you ask, and what do you check?
- Why ask it:
- Tests diagnosis of a common endpoint issue.
- A strong answer shows:
- Asking what changed, then checking updates, disk space, startup programs, resource use and possible malware before reaching for a reimage.
Question 4: How do you approach a problem you have never seen before?
- Why ask it:
- Shows how they learn on the job.
- A strong answer shows:
- Collecting error messages and logs, checking the knowledge base and vendor documentation, testing safely and escalating at the right point.
Question 5: Tell me about a fix you made that caused a new problem. What happened next?
- Why ask it:
- Tests honesty and care when making changes.
- A strong answer shows:
- Ownership, a quick rollback or correction, and a habit they changed, such as testing first or confirming with the user.
Tickets, prioritization and escalation
Help desk work is a queue. Look for a clear way of deciding what comes first and when to hand a ticket on.
Question 6: You start a shift with a full queue, a manager calling about their printer, and an alert that email is down for one office. What do you do first?
- Why ask it:
- Tests prioritization by impact and urgency, not by who is loudest.
- A strong answer shows:
- Tackling the issue affecting the most people first, telling the manager when to expect help, and following the team’s priority rules or service levels.
Question 7: How do you decide when to escalate a ticket, and what do you include when you do?
- Why ask it:
- Tests judgment about their limits and the quality of their handoffs.
- A strong answer shows:
- Clear triggers such as time spent, access needed or business impact, and a note with symptoms, steps already tried and user details so the next tier doesn’t start over.
Question 8: What does a good ticket note look like to you?
- Why ask it:
- Shows documentation habits that help the whole team.
- A strong answer shows:
- The problem in the user’s words, the steps taken, the fix or next step, and enough detail for a colleague to pick it up.
Question 9: Tell me about a time you couldn’t meet a promised response or resolution time. What did you do?
- Why ask it:
- Tests accountability and user communication when work slips.
- A strong answer shows:
- Updating the user before the deadline passed, setting a new expectation and escalating if needed.
Question 10: How do you spot that several separate tickets are really one bigger problem?
- Why ask it:
- Shows awareness of the difference between individual requests and an incident.
- A strong answer shows:
- Noticing patterns in timing, location or symptoms, linking the tickets, and alerting the team or raising a single incident.
User communication and service
Support specialists often meet people at a bad moment. Any interviewer, technical or not, can judge these answers.
Question 11: Explain how to [connect to the VPN or set up multi-factor authentication] as if I were a new employee who rarely deals with IT.
- Why ask it:
- Tests plain-language explanation, which a non-technical recruiter can judge directly.
- A strong answer shows:
- Short steps without jargon, checking understanding along the way, and patience.
Question 12: Tell me about a time a user was angry or upset when they contacted you. How did you handle it?
- Why ask it:
- Tests composure and service under pressure.
- A strong answer shows:
- Acknowledging the impact on their work, staying calm, giving a clear next step and following through.
Question 13: How do you handle a request from a senior leader that goes against policy, such as installing unapproved software?
- Why ask it:
- Tests the confidence to hold a line politely.
- A strong answer shows:
- Explaining the reason, offering an approved alternative and escalating to the right owner rather than quietly making an exception.
Question 14: How do you keep a user informed when a fix is going to take days rather than minutes?
- Why ask it:
- Shows how they manage expectations.
- A strong answer shows:
- Regular updates with a realistic timeframe, and a workaround so the user can keep working.
Security, access and documentation
Support staff hold the keys to accounts and devices. Look for habits that protect the organization even when a user pushes back.
Question 15: A caller says they are a manager locked out of their account and need a password reset right now. What do you do?
- Why ask it:
- Tests identity verification and resistance to social engineering.
- A strong answer shows:
- Following the verification process every time, whatever the urgency or seniority, and reporting anything suspicious.
Question 16: A user forwards an email they think is phishing and admits they clicked the link. What are your next steps?
- Why ask it:
- Tests security incident basics.
- A strong answer shows:
- Acting quickly through the security process, such as resetting credentials, checking the device and alerting the security team, without blaming the user.
Question 17: A manager asks you to give a new starter exactly the same access as a colleague. How do you handle it?
- Why ask it:
- Tests understanding of least-privilege access.
- A strong answer shows:
- Granting access based on the role and the right approvals, not by copying another account, and recording what was granted.
Question 18: Tell me about a knowledge base article or how-to guide you wrote. Who used it, and how did you keep it current?
- Why ask it:
- Shows documentation that helps users and colleagues.
- A strong answer shows:

- Some clients ask for specific certifications for help desk and service desk roles.
- A strong answer shows:
- Exact certifications and dates earned, with proof available if the client needs it.
Question 21: The role is [shift pattern, on-site or remote, location and any travel between sites]. Does that work, and when could you start?
- Why ask it:
- Rules out schedule and location mismatches early.
- A strong answer shows:
- A clear yes, or the specific constraint, and a firm start date or notice period.
Question 22: Are you legally authorized to work in [country] for this employer, and will you need visa sponsorship now or in the future?
- Why ask it:
- Confirms eligibility; ask every candidate the same question in the same way.
- A strong answer shows:
- A direct answer, recorded the same way for every candidate.

Red flags, and questions not to ask
- Would reset a password or grant access without verifying identity because the caller was senior or in a hurry.
- Describes troubleshooting as trying things until something works, with no clear order.
- Talks about users with frustration or contempt, or blames them for every problem.
- Cannot describe what they write in a ticket or when they would escalate one.
- Lists certifications or tools they cannot describe using in a real support role.
- Age, marital or family status, pregnancy or plans for children, religion, ethnicity or national origin, sexual orientation or gender identity. These are protected characteristics under the UK Equality Act 2010 and US federal law, and they say nothing about whether someone can do the job.
- Health, sickness absence or disability before an offer. You can ask whether the candidate needs any adjustments for the interview, and whether they can do the essential tasks of the job.

IT support interview questions: frequently asked questions
Still deciding?
Bring a live vacancy and we’ll walk through where automation ends and recruiter review begins.
Ask for real examples that test troubleshooting method, ticket prioritization, communication with users, security and access habits, documentation and escalation, such as a vague “internet is down” call or an urgent password reset from a caller they can’t verify. Add must-have questions on the systems they have supported, any certifications the client requires, shifts, right to work, start date and pay expectations, and ask every candidate the same questions in the same order.
Ask the candidate to explain a simple task, such as setting up multi-factor authentication, as if you were a new employee, and judge whether you could follow it. Ask how they would handle an urgent password reset from a caller they can’t verify, and listen for a firm, polite process. Confirm the systems and tools they have supported recently, and leave deeper technical checks to the client’s technical round.
It depends on the client. Some ask for CompTIA A+, which is earned by passing two exams, Core 1 and Core 2, or for ITIL 4 Foundation, the starting module in PeopleCert’s ITIL scheme for IT service management. Others care more about hands-on help desk experience. Confirm the client’s requirement before screening, and ask candidates for proof rather than relying on a resume line.
Keep the same questions and change the depth you expect. A first-line help desk candidate should show a clear method for common issues, good user communication and sensible escalation; a second- or third-line candidate should describe resolving complex directory, network or server issues themselves and supporting the help desk with documentation.
