GitHub Software Engineer interview questions

There were a total of four interview rounds: a recruiter screening, a hiring manager interview, and a loop consisting of system design and coding rounds. The interviews went very well, and after each round, the interviewers seemed highly impressed and mentioned that I would hear back from the recruiter soon. However, I was ultimately rejected because the decision came down to a very close comparison between me and another candidate. Additionally, the recruiter was not very helpful throughout the process, which made the experience more frustrating.
