HR was very friendly, asked basic questions-tell me abt urself, why sc, why PB, drilled down into finance-related parts of the resume, strengths/weaknesses. 3 person panel interview was conducted politely, genuinely interested to know more abt you. Top mgmt interview was more relaxed and more of a casual chit-chat instead of sounding out of technicals. Altogether 3 rounds of interview, first round phone interview, second round panel interview and last round with top mgmt.
