Below market pay. There's this mentality that employees cannot achieve an exceeds rating in performance, that there's always room for improvement, and this guarantees that you will never earn the highest raise possible.
The corporate culture is just that...corporate. Expect the usual corporate nonsense such as rah rah parties, lame events, company provided junk food from time to time, and a patronizing attitude as to why even if they paid you more it would never be enough.
Time off is pathetic. Sick time and vacation time share the same pool of hours. Planned a trip later in the year but got sick and used all your PTO? Too bad...looks like you're canceling your planned trip.
401k matching only happens once per year, and you only get the match if you're still employed with the company on December 31st, otherwise you forfeit the match regardless of how much you contributed throughout the year.
The company is run by a bunch of old guys who don't believe in remote work even though the job can literally be performed anywhere with a solid wifi connection. I think they just want to micro-manage.
