- it depends on people you end up working with (some teams are more remote, others are more always thinking of work up and you may get notifications at 3am, others are more chill and so on). You have to ask with which team you'll end up working and meet them.
- some projects may be vowed to failure but as upper management is pushing you have to do it even if you don't believe in it
- close to impossible to negotiate the pay outside the evaluation process ; personally I am below what I could get on the market (but I stay for personal reasons)
- the matrix and the 360 evaluation system is actually a trap for people that don't especially make friends in the office. You think it helps your progress but for people that have a life after work you don't know a lot of people from work (because work is as you guess it only work) and then during the evaluation process people that make lots of connections have better evaluations
- the big data part is kind of a protected kingdom and it is very difficult to enter in it. The idea is that big data is the source of income of Criteo and so the closer you get to that the greater is your power in the company but this is less and less true and other people should be valued as such because at the moment people working in non-big data areas are not valued as much.
