Interview Prep

Scenario-driven questions, organised by domain. Every question here starts from a system in a particular state, because that is how the round actually goes — "what is Kubernetes" is not a question anyone senior gets asked.

Each hard question is written with four parts:

• What the interviewer is testing — the judgement behind the question
• A strong answer — what a good response covers, and in what order
• A common weak answer — the shape of the response that loses the round
• Follow-ups — where the interviewer goes next if you answer well

Until this section is filled in, the Interview Questions section at the end of every case study is the fastest route to the same material — those questions are written against a scenario you have just read in full.
