Visa Inc. Software EngineeringData Platforms Team interview questions

Visa was one of the worst possible interview experience I have ever had. I applied through college career fair so the first round was in college. The first round was technical where the interviewer asked about my projects, few questions on multithreading, few on Hadoop etc. I was told I will hear back in a week but I had to follow up for a month extremely rigorously to hear back about the result. After 1 month, I had my second round which was with a manager. The recruiter had to reschedule the initially and the interviewer did not call the scheduled time. Later, after I told the HR, the interviewer called back and asked me few behavioral questions. It was clearly evident that he was so unprepared for the interview. Finally I had to follow up for about 2 months to hear a reject.
