There's a takehome which they give you 3 hours for, but shouldn't take you more than an hour and half. The recruiter I worked with was really great, and the takehome was well done. The rest of the process was a little more offputting. They claim in the takehome that they prefer to ask questions that reflect the real world, but I got a LC hard, plus what is in my opinion a unreasonable system design question--basically, being asked to design Netflix.
I got feedback from the process, which was great, but one piece of the feedback was that I was "curious to a fault," because I had asked too many questions about what it'd be like to work there. It's absolutely insane to me that I got dinged for trying to do my own due diligence about what it'd be like to work there. I'm sure I could've done better on the system design rounds and it wasn't just me asking too many questions, but my god, do I feel like I dodged a bullet.

Interview
Single exam no human interaction. The exam was like a college test, something completely unrelated to modern field work. Seemed a bit off base. Definitely didnt seem like a realistic approach to finding real humans to fit for a company.
