Pros
Just ok bands <=7 IBM 1 Now It's only somewhat ok for people of band 7 or lower . They manage to find work as clients request resources of lower bands . Arrogance of gbs is in its very high billing rates which are not normaly commensurate with the performance of its employees. Hence clients prefer other vendors like Tcs , Infosys for major chunk of work while handing ibm gbs only the small remaining part.
Cons
New joiners on band 8 or above don't survive for long after finishing their first billable assignment, as they don't have contacts to survive .UTE PIP is specially devised to clean up bench periodically. Remember, GBS does nor care for seniorty or experience , not even past performance for people on bench . Imagine people with 20+ years experience being let go for lack of billable work , they have no consideration for his family , financial resonsibliies etc .
