Don't interview here. I talked to both of the founders before interviewing with a "ML engineer." He asked a few vague conceptual problems about image processing, no programming questions. When I got rejected, I asked why, and the feedback was that my "programming skills" aren't strong enough. Ugh. They seem disorganized in their interview process, and, worse, if you scroll down past the recent glowing reviews, their Glassdoor reviews are terrible, particularly about how they treat their women engineers.
