Cognizant — offer letter not received (interviewed at bagmane tech park on 18 august 2018)

Address: Bangalore, Karnataka, 560066

I had interviewed for an sfdc profile on 18th august 2018.

I had cleared all the rounds and then i was asked to fill up a form.

The hr told me that i was selected and i even got a cup as an acknowledgment, and was informed that i will be getting the offer letter within a week.

However, it's been 2 weeks already and i have not received any offer letter.

Kindly help me on this.

Thanks
Prachi
