Technical interview preparation

Technical interviews vary by role, but the failure mode is stable. Candidates name tools and skip the decision. A useful answer lets someone else reconstruct why the work was done that way.

A structure that holds up

• Problem: who was blocked, and what constraint mattered.
• Approach: what you chose, in one or two sentences.
• Alternative: what you did not do.
• Check: how you knew it worked, including a check that failed first.

During the round

If you do not know, say what you would look up and what you already understand. Guessing a precise API or a company-internal system is worse than a clear limit. This site’s technical round will not score code correctness. It practices the explanation.
