Interview taken my multiple people across different roles if the interview is for category. You'll most likely be on a third party payroll and the expectations are minimum. But the main thing is that they will explicitly ask you to be available close to 18 hours a day to spend for work, though not completely, but yes definitely it will take most of your time

first step is screening after they take aptitude test and 2-3 round of personal interview like technical interview, managerial interview and HR interview. after that they provide offer letter to selected student.
