Behavioral Technical Coding System Design
I went through a two-stage interview process. First, there was an HR screen where I talked about my tech background and salary expectations. Then, I had a technical interview with two engineers, a team lead and a manager who also had an engineering background. They asked me about Go, databases, system design, and some behavioral questions. After the discussion, we had an online coding task. Unfortunately, I received a rejection email stating I lacked basic CS knowledge, without specifying what areas. The interview environment felt high-pressure; I was interrupted frequently, the interview lacked structure, and the requirements seemed to change as we went. It felt like the interviewers believed they were the only ones with the correct understanding.
