Sample technical support engineer interview questions

8 of the 13 questions Ava can ask for this role, one or more per skill. In a real session she adapts them to your level and follows up on your answers.

  1. Q1Troubleshooting & root causeEntry level

    A customer says the product is slow but gives you no other details. What would you ask them first?

    A strong answer: Asks what exactly is slow, since when, for whom, on which device or network, any recent changes, and whether it can be reproduced.

  2. Q2Technical knowledgeEntry level

    In simple terms, what happens when you type a web address into a browser and the page loads?

    A strong answer: Mentions looking up the address to find the server, connecting securely, sending a request, the server responding, and the browser rendering the page.

  3. Q3Customer empathyEntry level

    A frustrated customer tells you this is the third time they have contacted support about the same problem. How do you start the conversation?

    A strong answer: Acknowledges the frustration sincerely, reviews history so they do not repeat themselves, takes ownership, and sets clear next steps and timing.

  4. Q4Logs, tools & scriptingMid level

    How do you use logs or monitoring tools to narrow down a problem? Give me a real example.

    A strong answer: Names specific tools, filters by time, user or request, correlates errors across systems, and explains what the logs revealed.

  5. Q5Escalation & engineering collaborationMid level

    How do you decide when to escalate a ticket to engineering, and what do you include when you do?

    A strong answer: Escalates after reasonable investigation or for high impact, includes clear reproduction steps, environment, logs, impact and urgency.

  6. Q6Ticket & incident handlingMid level

    Several urgent tickets arrive at the same time. How do you decide what to work on first?

    A strong answer: Prioritises by business impact and number of users affected, checks for a common cause, communicates with everyone waiting, and asks for help when needed.

  7. Q7Composure under pressureSenior

    A major outage is affecting many customers. What is your role in the first hour?

    A strong answer: Follows the incident process, confirms scope, coordinates with engineering, posts regular status updates, handles incoming tickets consistently, and stays calm.

  8. Q8Documentation & knowledge sharingSenior

    How would you reduce repeat tickets for the same issue across the whole support team?

    A strong answer: Uses ticket data to find top drivers, writes or improves help content, shares fixes internally, and pushes product fixes for root causes.
