I applied online. The process took 1+ week. I interviewed at Acumen (Burlingame, CA) in Oct 2019
Interview
Short phone call. I was asked some questions about my prior experience, things like what type of datasets have you worked with before, what programming languages do you have experience with. Also some basic questions like strengths/weaknesses.
The first two rounds was phone call and then followed by the last round interview. Most of the questions were based on resume and past project experience. Every interviewer is nice
