Startups have some startup problems. Array has done a great job addressing many of them, but it wouldn't be fair to say there aren't any. That said, take these with a grain of salt: if you're applying at a tech startup, you should be prepared for them already. Turnover at the mangement+ level is moderate, although within expectations for a tech startup I think. Turnover is high everywhere in tech, too. Reorgs happen frequently. This is just a most-tech-companies thing, doubly true for startups. You have to be able to pivot to new teams/squads/reporting structures with grace and agility to keep up. Highest level executives still have a hand in day-to-day operations. It can be intimidating if you're not used to it, and happens naturally while companies accelerate hiring during a growth phase. Eventually it will change, but worth noting that some executive interaction skills will help.
