I am sonia pan. I have given interview on sunday 13th may 2018 at cognizant kolkata branch for junior data analyst. I cleared both rounds aptitude and hr round. Hr asked me about shift in duty and told me that they will contact me through email. But i m not selected but didn't understood why i m not. I heard that because i m b. Pharm pursuing so they didn't select me but in document they clearly told that they want b. Pharm pursuing. I don't know what to do. Where is the clear process in interview? Us mnc company in india so they do anything they want. If i will not get response after posting this complaint then surely i have to file a case against them.
