If you are even considering joining as a SWE, turn around, walk away. I was fortunate enough to get through the pre-screener and the takehome, which took way longer than they estimated, and had an onsite with upper management. The takeaway here is if you yourself don't function like an entrepreneur or have any history in working for a super young start up then they don't want you. They aren't going to care about your technical accolades. Basically they want staff level experience, put on a senior level title, and at the pay rate of a mid level engineer. There's a reason why they've had their job posting up for months now when its a buyers market.
