Senior Backend Engineer Interview Questions

2,796 senior backend engineer interview questions shared by candidates

The main "question" was a techincal interview, where I had to setup some start to end mini project, the time frame is a round 1hr and one is asked to prepare the environment in advance. I have seen one review here on Glassdoor which points out bad guidance through the interview process. I would argue with this, it is an interview where a persons skills are being tested. While the interviewer is supposed to guide, the interviewee is the one who should lead through the problem and communicate clearly if guidance is missing. I faced some struggles throughout the process but I communicated them clearly and got guidance through those issues.
