Some detailed questions towards the presentation I brought, and the code review was more likely to depend on what the interviewer wanted to know. He asked me which function I wrote is the one I wanted to walk him through. I felt the 1-on-1 call was just an extension of the code review because I met the same guy and he insisted we should go through more about the take-home assignment. He was super interested in implementing unit testing.
