Initial interview is all about your work experience, preferences in work and availability to match with their client. Just know your cv well and research about the company also because they will ask about it.

They will send you an email where you'll schedule your preferred date and time for the interview. Once confirmed you'll receive a zoom link. The interview started by telling something about yourself that's not job related, so mostly personal questions. Next is they'll ask you about your educational background. Then you'll walk them through on your daily responsibilities on your previous jobs. Lastly, they'll ask you expectation salaries and preferred set-up and working hours.
