Deloitte Performance Management - Analyst interview questions

Applied through monster. They have sent a mail for walk-in, Hectic interview process. 700 candidates appeared for the interview. Rounds include: Jam session, HR interview, Communication Skills Test - Versant and Belit Test. It tooks more than 9 hours to come out of the office. They are not well prepared for the interview. You also have telephonic round to understand about your experience and reason for leaving. After 2 weeks they called for Face to Face interview. One at executive level and next at manager level. They scheduled interview at 2 pm. It took another 5 hours to come out. But the interview was actually less than 30 minutes both together. They make you wait. Another 2 weeks passes still no call from them.
