There must be 4 to 5 rounds and that totally depends on the availability of the ceo . The rounds can be increased , just to engage you only. You can feel yourself while interacting process during interviews, the questionnaire are mostly same in all the rounds. Most silly questions asked everytime: Tell me about yourself , In every round your fluency will be checked. At last the HR round , salary discussion round. The salary is mostly low in all posts , so don't expect too much from this question in order to earn. The HR ecosystem is not so good, salary is poor and they ask to submit your 10th or 12th document as a bond.
