Wrike Senior Software Engineer interview questions

I submitted my resume via the website in February and received the first response from HR at the end of April. After that the process moved much faster and by mid-May I had completed all interview stages. In my opinion there were too many calls with HR throughout all stages. 1) Initial HR Interview A short standard introductory call. Nothing particularly special. 2) Technical Interview I was asked to discuss a solution in detail. There was a hierarchical structure of entities and I needed to implement validation rules between them taking into account edge cases. Then I had to write the minimal amount of code based on our discussion choosing the simplest possible implementation. During this time the interviewers left me alone and muted their microphones and turned off their cameras. After that they reviewed the code and we discussed their feedback. Finally we talked about broader potential issues that could arise from this implementation. 3) Cultural Fit Interview A very long and to be honest somewhat unclear interview. The questions were mostly about collaboration with colleagues, attitude toward work, and similar topics.
