I got questions from people on multiple teams over several interviews. Considering just how many interviews I had, it was actually a pretty chill process that didn't feel like a slog.
I applied online. The process took 2 weeks. I interviewed at MediaMath (Chicago, IL) in Dec 2019
Interview
MediaMath had a total of 3 interviews. The first two were screening interviews to check for my interest in the company and overall competency. This went well. The final interview was a 3 on 1 technical interview. The technical interview was digging into more what I've done than what I know. There wasn't quiz questions like 'What's the difference between a dict/list in python' since it was on my resume - rather the interviewers were interested in the scale of deployments I had conducted.
