There were 2 rounds of AC, both were long. First round I had 2 interviews and 3 written test. The interviews were not that hard. Just make sure you think about the context of the case (the client). Second round interview was composed of 2 interviews, 1 presentation and 1 group discussion. Again the questions were not hard, but the presentation preparation time was short and the material provided was a 20page long document. Time management is important. I got rejected because I didn't answer the competency based questions well.
