Slowly the culture has disappeared and been replaced with directives from the exec team to shut up and work. Work-life balance is either great or non-existent, but vacation is now only reserved for engineers who have been there long enough to be irreplaceable. It wasn't uncommon for people to either take 4 days of vacation and be shamed for taking time off because "we're busy" (we were always busy), or 8 weeks and thanked for their service often. You're either a favorite who gets promoted often and praised, or you're forgotten and glossed over every year. Most of the company falls into the second bucket.
All the perks we had have been taken away slowly, with the main perk now being "a paycheck". Compensation is on the low end (no bonus, decent base, bad equity), and all the issued stock options I got while working there are worthless now after a fundraise (a nice way to treat the people who helped get the company where it is today). Employees still there have to re-vest all their options.
Diversity is something we talked about, but typically hires were either H1Bs or experienced hires, so not a lot of room for diversity.
