Vantaggi
If you are a fresher with no job offers other than this, then join by all means. It will be a life experience, you will learn a lot. About what to avoid in life at work place. A good stepping stone.
Svantaggi
1) If you are a fresher and have choice of offers then avoid this company or you will regret it. 2) If you have prior experience and quit your job present job to join this company then you will be dumbest and most stupid person on earth. 3) All the good rating this company received so far at Glass doors is a deliberate attempt by HR to improve the company rating. They look for favorable or gullible employees and ask them to give a 5 star rating to improve the Companies rating in Glass door. I know this because some of my colleagues were approached by management.
