There were 2 Online tests including programming as well as aptitude based on role you are applying (moderately difficult). Once you clear both the test you may get the call in a week or two regarding the face to face interview. There will be 3 rounds of Technical discussions, all 3 rounds would be started by your resume screening with having the technical problem statements to solve and answer the queries. Questions may vary from panel to panel as well as interviewer. You would be judged purely based on your skill set and the way you handle the problem statement and answer the questions. I would suggest if you are technically good make yourself better enough in presenting, That's the foremost important quality you would be looked for in any company's interview process followed by the amount of knowledge you posses will help you successfully crack the interview and help you achieve fruitful results. If you are experienced you will be definitely asked about your previous job role. So make sure you justify the same positively.
