Backend Software Engineer Interview Questions

2,339 backend software engineer interview questions shared by candidates

Mix of tech questions and experience-focused questions. The tech questions were based on problems presented by other engineers at the company. The interviewers were kind and encouraging even though I don't think I did well on the coding parts. Seems like a good company and although I'm disappointed I didn't get an offer I think they are worth interviewing with if you are looking for a dev position.

The coding round of the onsite loop is similar to an algorithms question, but the focus is not necessarily on providing a solution with optimal runtime but more so on making sure you can clearly think through a solution, write understandable code.

I had four rounds of interviews. The first round was a coding round where I was asked a leetcode hard problem, the second round was a low-level system design round which was pretty easy. The third round was a high-level system design round and finally a behavioral round with the hiring manager.
