Screening questions for technical support specialists.

Troubleshooting method

Good specialists isolate one variable at a time instead of trying fixes at random.

Plain explanation

The user needs to understand what to do next, not how the system works.

Escalation and documentation

A clear ticket to engineering saves hours. A vague one costs a day.

Patience with users

Users describe symptoms, not causes, and often in the wrong words.

1. 01

   Tell me about the hardest technical problem you solved for a user. How did you narrow it down?

   Strong answer

   Walks through a sequence: what they ruled out, what they tested, what the evidence showed, and what the cause turned out to be.

   Weak answer

   Jumps to the fix with no explanation of how they found it, or describes trying things until something worked.

2. 02

   A user says “the app is slow.” What are your first questions?

   Strong answer

   Asks what exactly is slow, since when, on which device and network, and whether others are affected, before suggesting anything.

   Weak answer

   Tells them to restart or clear their cache without asking a single question.

3. 03

   Explain what a browser cache is, and why clearing it sometimes fixes things, to someone who has never heard the term.

   Strong answer

   Uses a simple comparison, keeps it to a few sentences, and ends with what the user should do.

   Weak answer

   Uses more jargon to explain the jargon, or can’t explain it at all.

4. 04

   Tell me about a time you escalated an issue to engineering. What did you put in the ticket?

   Strong answer

   Lists steps to reproduce, expected versus actual behavior, environment details, logs or screenshots, and customer impact.

   Weak answer

   “I sent it to the dev team” with no detail on what they handed over.

5. 05

   You find a workaround that fixes the problem, but you don’t know why it works. What do you do next?

   Strong answer

   Gives the user the workaround, then records it and flags it so the root cause gets looked at.

   Weak answer

   Closes the ticket and moves on.

6. 06

   A customer insists the problem is on your side, and you’re fairly sure it’s their network. How do you handle it?

   Strong answer

   Doesn’t argue. Runs or suggests a test that shows the answer either way, and stays open to being wrong.

   Weak answer

   Tells the customer it’s their problem and ends the conversation.

7. 07

   Several tickets with the same error arrive within an hour. What do you do?

   Strong answer

   Spots the pattern, raises it as a possible incident with the right team, links the tickets, and keeps customers updated.

   Weak answer

   Works each ticket separately without telling anyone.

8. 08

   How do you learn a product you’ve never supported before?

   Strong answer

   Describes a concrete approach: using it as a customer would, reading past tickets and docs, shadowing, and noting gaps in the knowledge base.

   Weak answer

   “I learn fast”, with nothing to back it up.
