Very little career mobility within the company
No 401k match
Has periodic layoffs. I have seen lot of people who get rolled off the company if they can't make partner.
The green card policy sucks big time. There is no clear policy that is communicated to the employee. It is very much left at the manager's behest. Managers usually bait and switch the employees using the green card as a tool to keep them. HR is not helpful in resolving such matters.
Overall, this is a very top down company. It talks a lot about diversity and equality, but if you peel away the layers , none of it is being practiced, in reality. In my case, my manager kept promising a green card filing for 2.5 years without actually filing it, but always making sure to 'bait and switch'. HR will deny any meetings or calls. Immigration team will work in collusion.
To summarize:
No diversity at leadership that can understand issues related to immigration
BCG managers do not fully comprehend issues faced by immigrants
BCG leadership (at Director+ levels) have very little training about the immigration process in this company
HR does not fully comprehend issues faced by immigrants and are not very helpful
The Green Card process does not provide transparency to the employees, leaving them with zero control of their own situation
Needless to say, the different players in the BCG immigration team have any accountability to employees as the process itself doesn't call for it
