Everything is pretty hostile. Be prepared for people to make fun of you in slack when you don't know something that's deemed 'obvious' by someone else. There's a reason that minorities don't last as long as their white male peers, especially in more technical areas. Lots of inclusion hand waving from senior people that's not mirrored on the ground.
Borderline cultish, no healthy distinction between work and personal life. You'll be referred to as 'family' expected to give up personal commitments, and your LinkedIn should now contain the daily Databricks stories and milk your personal network for people to join the 'family'. Once someone leaves, they might as well be dead to the company. Next to no one gets a leaving card, gift, or even an announcement that they've gone. You only notice when you can't slack them anymore.
Not a con as such, more a word of warning: everything is utter chaos. Don't think you can do anything as bold as have a plan for the week, someone will steamroller it with the latest "urgent" request that you absolutely have to help them with because they lacked the foresight (and incentive) to plan.
