Hows Tech Mahindra with regards to SAP Projects

Hi all, one of my friends recently got offer from Tech M and its a fat package(atleast for us) of 30+ LPA. But one of our other friends(SAP Non-technical) once was asked to resign because his package was also similar and once the Project was finished he was indirectly asked to put papers, this happened some 2 years before. Can folks from Tech M enlighten is Tech M really that risky ?
