Is Mu Sigma Still a good company?



I am a final CSE student and i have wanted to join Mu sigma.I want to lead a career in Data Science for which i have heard that Mu Sigma is the best place to start.But due to recent events of its top employees leaving the company,im having second thoughts about joining the company.I dont want to work for 3 years and let it go to a waste.My priority is learning as much as i can and also to get the brand name of mu sigma.

Keeping all this in mind, do u think Mu Sigma is still a good place to join as a fresher?
