Phone interview - 45-minute call with an engineer. There were two problems: * One warm-up problem, about the difficulty of FizzBuzz. * A few minutes afterward for me to ask questions. All in all, it was thoroughly enjoyable. It felt more like pair

One of the interviewers was 15 minutes late. I expected a coding question but was asked something quite math-heavy. He asked me whether I know convolution (which might make sense given it was likely an ML role).

Initial phone screen with human resources. One video interview that was a technical interview asking about algorithms. On-site interviews at the Boston office that were technical, with four separate interviews.
