Pros
1. Young, clever and friendly environment 2. Good compensation and bonus 3. A lot of small additional benefits - snacks, taxi, dinners, events.
Cons
1. A lot of disappointing bureaucracy moments Main short story: There is some bonus of first year for researchers, which accruing unevenly - 1/3 of sum for first half of year and 2/3 for the second. All bonuses are paid once a year (in the March). I started in July, so I got only 1/3 in the first "bonus time". And then I left the company in September, before next "bonus time" (by mutual agreement, with some benefits, but still). I formally worked this first year, but company didn't payed me 2/3 of first year bonus, explaining that bonus can be payed only once a year and it's generally discretionary. That was very disappointing.
