Dropped off resume at university career fair, and received an invitation to participate in a one-hour coding challenge shortly after. The coding challenge was done through HackerRank but in a designated room on campus. I wasn't able to finish an optimized solution in time and only passed something like 6/10 test cases (remaining ones timed out), but still received an on-campus interview invitation within a few hours. On-campus interview was an hour long and had only one question, with the coding done through a shared notepad website. It didn't take too long to complete but my interviewer asked a lot of followup questions, mostly What-ifs, that filled most of the remaining time. I thought I did pretty well and had reasonably good answers to all of the questions, but received notification about a week later that I didn't make the on-site.
