सामान्य प्रश्न

1. 1. Walk me through a technical system you designed end-to-end. What architecture decisions did you make and why?

   उत्तर मार्गदर्शिका: Frame your answer as context, constraints, alternatives you rejected and a measurable outcome. Speak in metrics (latency, cost, throughput) and acknowledge real trade-offs.

2. 2. Describe the last tough code review you received. How did you process it and what changed in how you write code?

   उत्तर मार्गदर्शिका: Show openness to feedback. Cite the specific observation, what you refactored and the habit you adopted to avoid the pattern going forward.

3. 3. Tell me about a critical production bug that you fixed. How did you isolate it, what tools did you use and what came out of the post-mortem?

   उत्तर मार्गदर्शिका: Walk through detection (alerts, logs, metrics), the first hypothesis you validated and the safeguard you added so it cannot recur silently.

4. 4. When you have to choose between shipping speed and technical quality, how do you balance it?

   उत्तर मार्गदर्शिका: Avoid the political answer. Give a concrete example with explicit trade-offs: business deadline, accumulated tech debt, risk of the change and why you yielded.

5. 5. Why are you interested in this role specifically and not another at similar seniority?

   उत्तर मार्गदर्शिका: Connect three dots: what the company does, the technical problem that excites you and the skill you want to deepen over the next 12-18 months.
