How to use this page
Don't memorise answers. For each question, read what the interviewer is looking for, then practise answering out loud in your own words with a real example. The notes describe strong answers and common red flags — they are for your prep, not a script.
Troubleshooting
1 questionA customer reports the product is 'not working' with no detail. How do you get to the root cause?
IntermediateWhat the interviewer is looking for: Strong answers ask targeted questions, reproduce the issue, check logs, and isolate methodically. Guessing at fixes without understanding the problem is a red flag.
Customer Service
2 questionsHow do you handle a frustrated customer while still solving the technical problem?
IntermediateWhat the interviewer is looking for: Look for empathy, acknowledging the impact, staying calm, and focusing on resolution. Getting defensive or matching their frustration is a red flag.
How do you turn a support interaction into a good experience even when the news is bad?
BasicWhat the interviewer is looking for: Strong answers set clear expectations, keep the customer informed, and follow through. Going silent when there is bad news is a red flag.
SQL
1 questionHow do you use SQL to investigate a customer's data issue?
IntermediateWhat the interviewer is looking for: Strong candidates query to confirm the state of the data safely, using read-only access appropriately. Running risky queries on production without care is a red flag.
REST APIs
1 questionHow do you use API knowledge and logs to diagnose an integration failure?
AdvancedWhat the interviewer is looking for: Look for checking request/response, status codes, auth, and payloads, and reproducing with a tool like Postman. Not being able to read an API error is a limitation.
Escalation Management
1 questionWhen and how do you escalate an issue you cannot resolve?
IntermediateWhat the interviewer is looking for: Strong answers escalate with clear reproduction steps and context after doing due diligence, not too early or too late. Dumping unclear tickets on engineering is a red flag.
Technical Documentation
1 questionHow do you write documentation or KB articles from the issues you solve?
BasicWhat the interviewer is looking for: Look for turning repeated issues into clear self-serve articles, reducing future tickets. Solving the same issue repeatedly with no documentation is a red flag.
Ticketing Systems
1 questionHow do you manage a queue of tickets against SLAs?
BasicWhat the interviewer is looking for: Strong candidates triage by severity and SLA, keep customers updated, and manage their time. Letting tickets breach SLA silently is a red flag.
Product Knowledge
1 questionHow deep is your product knowledge, and how do you keep it current?
BasicWhat the interviewer is looking for: Look for genuinely understanding how the product works and staying current with releases. Surface-level knowledge that forces constant escalation is a limitation.
Communication
1 questionA customer asks for something the product cannot do. How do you respond?
BasicWhat the interviewer is looking for: Strong answers are honest, offer workarounds, and log the feature request, without misleading. Pretending it is possible is a red flag.
Attention to Detail
1 questionWhy is attention to detail important when reproducing and reporting bugs?
BasicWhat the interviewer is looking for: Look for precise reproduction steps, environment details, and evidence so engineering can act. Vague bug reports that bounce back are a red flag.
Linux
1 questionHow comfortable are you on Linux and the command line for investigating issues?
IntermediateWhat the interviewer is looking for: Strong candidates can check logs, processes, and connectivity from the shell. Being unable to investigate beyond a GUI is a limitation for technical support.
Problem-Solving
1 questionHow do you balance closing tickets quickly with truly solving the problem?
IntermediateWhat the interviewer is looking for: Look for solving root causes rather than applying band-aids just to close tickets. Prematurely closing tickets that reopen is a red flag.
Behavioural & role-general
2 questionsTell me about the hardest issue you solved. How did you approach it?
BasicWhat the interviewer is looking for: Look for structured diagnosis, persistence, collaboration, and a clear resolution. A story with no method is a red flag.
How do you feed recurring customer problems back to product and engineering?
BasicWhat the interviewer is looking for: Strong candidates spot patterns and advocate for fixes, acting as the voice of the customer. Just closing tickets without surfacing trends is a red flag.
