for the first question(solutioning) Interviewer was expecting the only answer which he knew for it. and when he didn't get it he didn't take much interest. he asked me to leave in just first 2-3 minutes. it took me 2 hour to travel from Noida to Gurgaon and all i got was 2 minutes. i was already selected in TCS by this time and i had really good Big data skills with 3 years of exp but Interviewer was too stubborn. i am not angry because i didnt get selected but i was really angry that how casually UHG treats candidates in interview
Foram perguntas básicas, nada técnico.
