They expect you to work all the time. There are metrics that measure if you are slacking even a minute off, and your team lead will present you data every month on how bad you and everyone else worked, and how hard you should be working - no matter what is your reality, they only care about crunching numbers.
There are always waiting lines, and backlogs, and piles of old work that makes customers furious because Wise is selling something that's not true (instant transfers). Get ready to be called a biyatch and shouted at on a regular basis. Your team lead and bosses will not care, no matter how much abuse you take, you should be able to take it, and 'relax and release stress at home' apparently that's what your free time is for.
They say that you can move on if you prove yourself, that's only true if you are friends with the right people, and you keep your mouth shut. Your bosses will literally sit through meetings all day, not doing nothing, but then come down raging on you to work harder.
Forget about going to any of the fun events the company organizes, or having any holidays, in CS they don't allow you to do that. They try to lure you in with that, but essentially thats only for the fancier positions.
