Hiring process is very cumbersome. It takes 1 month to complete all the interview rounds. Interview rounds are also exhaustive. Around 4-5 rounds are conducted. The more you ask the more are the chances that the offer will not come even after doing excellent in the interview. Referrals are encouraged and internal movement is also consider. During the offer wait period, the key is to remain connected with the manager if he/she responded positively to your interview.
