Pros
If you are a robot or a shark the job is for you You will be not alone looking for a new job and to complain about your job You will be congratulate when you will resign (good people and talented people quit the rest are being promoted)
Cons
Partners are promoting work/life balance but if you dare come home before 8pm you will receive bad feedback. Rating is a good KPI to fire people. Managers will make your life a hell, even the "nice" or "easy" job will be difficult because the manager will expect from you the impossible. Giving 100% it's not enough you have to give 150%, but be careful the budget is only 80% and you need to give your time to the firm. If not you will receive bad feedback and bad feedback end with a firing meeting from people you don't know. Opportunity = job that nobody wants to do
