I applied online through Naukri portal in December 2019. Got a call after 3 days and interview was scheduled in January, 2020. Only 1 round was there with US managers. Informed me about result after 3 weeks that i am not selected. After 2 months they call me and say the person who has been appointed is not joining and promised me to send offer letter later day. But later day they informed me that they are looking for another options. My suggestion is if you are not sure and not sync up with US manager don't promise the candidate about offer letter.
