Attended an interview for two teams: AIDE and SDWAN. The questions were straightforward, with many domain-specific and bookish questions. If the HR or hiring team is not interested in providing feedback, please do not waste the candidate's time. I see the job description says a non-network background can apply, but during interviews, candidates are judged only on network questions. I feel this is absurd and not open-minded.

String-specific questions, difference between Python/Go, custom data structure design.
