1.) Dress code is the biggest issue. For example some one has bleeding from his foot , then also you have to ware shoes , other wise securities will ask to sent the mail to HR.
2.)After deploying in the client , they will not listen a singe thing of any employee. In my case i have joined as a Developer but by writing the false mail they deployed me in a manual testing project. When i asked them for the release they took 7 months for it.
3.) They dont have that much project. So if some one release from the project they will tell to go to Trivendrum or kochi. or else put down the paper.
ETC...........
