Pros
For students who are from colleges where placement scene does not cross ~4ish lacs, I genuinely think that MountBlue is doing a great job of training them and placing them in companies that would otherwise not even give them a chance. I personally got deployed in a company where many IITians and NITians and students from other good colleges work. Plus a lot of us got offers around 8-9 LPA I think you get the picture
Cons
The only actual con I would consider is that they give you ~26K every month for the deployment period ( ~1year -- sometimes 13 months ) and take the rest of whatever you are actually earning but again, considering other service based companies, thats the amount I would've gotten. Also, remembered at the last moment -- no PF bruh.
