There were 4 round of interview. First there was a written test and then it was followed by an interview with the Lead. They mainly focused on what you have worked and how deep you know. Other than that technically it was an ok interview. after that there were second round with mobile team lead which was again a normal interview with highlighting your achievement. Third round was with CTO and CTO sounded really straight forward and to the point. He believes in knowing the vision and telling what is company's vision. The last round was with HR head where there were behavior related questions.
