Began with an initial 30 minute screening interview with HR followed by a 1 on 1 with the manager, 3 hour long online technical interviews, and a final onsite interview.
Four rounds of technical/coding questions, 30 min - one hour each. Interviewed with three engineers, a technical manager, and upper management. Everyone was kind and the HR rep was very helpful throughout.
I applied through university. I interviewed at HPR (Chicago, IL) in Sep 2020
Interview
Met with recruiter at career fair to being process:
90 min HackerRank: Must be completed in C but pretty straightforward
~15 min Recruiter Phone Screening: Talk about projects, emphasis on networking/c
2-2 hour interviews with devs: mix of ds questions in C and some bitwise operations. Found the ds questions were leetcode easy level.
2-45 min with more senior devs: more simple ds questions. Then went through a list of very specific C/linux development questions. Was caught off guard by these. Nothing too unusual, but I had not coded a networking project recently so missed a lot of them.
