first round of technical interview and next will have managerial round of interview then we might have Client round of interview based on the project in which we will be assigned

The process is very smooth, Ideally, it takes 3 rounds 2 pure technical and 1 more towards HR. Technical rounds are more towards indepth knowledge of your role, scenario based question, how to handle the robust testcase scenarios etc and 3rd round is more towards Managerial .
