Referred through a friend, had a few quick informational calls then was sent the take home assignment, followed by onsite. The take home was a decent problem though it took a while, and I was told I "nailed it". They made me create some slides about it which I thought was strange because the take home assignment was in presentable format, and when I got there it seemed like no one had really looked at my take home. People were nice to me, but scheduling was a mess; they kept on pushing back and moved my onsite at the last minute. I didn't get asked that many technical questions when onsite, but I got feedback saying my ML/modelling was a concern. Given I had to do a lengthy take home modelling exercise, I am confused but I suppose there could just have been more experienced candidates.
