You will have 5 rounds of interview process. But mostly first 3 are critical. Being honest takes you long way. Basic Java programming , SQL and basic common sense should do the job. Solving the problem and explaining your strategy is the key. All of the interviewers are very friendly and they comfort you during the interview process. Like I said earlier, be honest and explain how you can perform your work activities with transparency and protect the integrity of the company and stick to the core values does the job.
