Tata Consultancy Services — about joining to tcs

I had cleared my one subject during summer semester which totally fine. Because my college is autonomus body so i can do that and get degree same as other and normal. So chennai branch told me i can't join company. But one of my friend joined hyderabad branch, who had same situation. His ct reference number is ct[protected]. So i think this is partiality. And i totally deserve to join company.
