The first call was from a recruiter to learn more details about my background and to set up the first technical phone interview. My first phone interview went very badly because I had requested the interview be in Python, but the interviewer asked me to implement C code. I reached out to the recruiter, explained the situation, and was able to secure a new phone interview, which I passed, leading to the on-site interview. I had five 45-minute interviews with an hour-long lunch break (the break was still on-site).

The main topics were algorithms, data structures, and graphs, and knowing if you knew the built-in library functions well enough.
