I went through multiple interview steps: an initial conversation with an internal recruiter, a take-home technical test using the company’s library, and a collaborative coding session, again using their library. Unfortunately, I didn’t pass the whiteboard session. In that last interview, the interviewer openly admitted from the start that they were not an expert on the topic. The task was to design classes for the existing engine together. However, a significant amount of time was spent on an example that turned out to be not relevant for the core part of the interview. My impression was that the interviewer had a specific solution in mind and was not receptive to alternative approaches. This made it difficult to engage in a true collaborative design discussion, and I had a strong sense I would not pass. My suggestion to the company: ensure interviewers are well-prepared and open to different perspectives, especially in technical and design interviews. This would make the process fairer and more productive for candidates.
