Interview process

Was referred so probably skipped some steps. The recruiter and first round was very friendly, but the person who debriefed my take home was not. Ultimately was rejected because they said they wanted someone more experienced but the process felt very dragged on.

Tips from the candidate

I would brush up on fundamentals, and also for this kind of data just use linear regression. No need for anything fancy.

Company culture

It was fine. The last person who interviewed me was a bit hostile/adversarial.
