Cognizant Technology Solutions — offer letter not received - still awaiting

Address: SB Road, Pune, Maharashtra

I completed the interview process on apr 27, 2019 in pune. I got selected for the position and hr told me that i should receive the offer letter within 3 weeks. I did not receive any communication in 3 weeks. I kept following up an now they are saying that this position is on hold.

This is very unprofessional. First they offered me a position and did not communicate anything about this hold. When i followed up number of times on different email ids, they just sent me a one liner saying that the "position is on hold".

Position: data engineer. They offered me sr. Associate

Any help regarding this is appreciated.
