Wells Fargo Summer Analyst interview questions

One straight forward interview. Mostly behavioral, but one technical question that was basically "what is a for loop." There were two interviewers who were easy to talk to. This was at a college CS career fair.

There were 3 rounds in the interview process. Technical round ,managerial round and hr round in the end was asked . I was eliminated in the managerial round The process was smooth and the interviewer in the first round was very kind but in the second round the interviewer was tough and asked a question out of the resume also.
