Firstly there were no HR when I was been interviewed, they sit in the Bangalore office. The first round was of aptitude with 15 questions. After submitting those you'll be asked once again over face to face. Then there will be face to face technical round where MySQL queries will be asked like join queries. Final round will be of director round, where he will explain you about company and will ask for commitments for at least serving them for 2 years
