Received a call for an interview this month on short notice and I've attended the interview on the same day for the client Publicis Sapient. The interviewer was a westerner or American who took the interview. It was going well and I had hope of getting the offer. The very next day I received a call from NLB HR Neha Yadav conveying to me that the interview result was positive and asked me to send my certificates and IDs as soft copies. When I asked for the offer letter, she told me that they need to send the details to the concerned team to release the offer. I have sent all the requested documents. On the third day, I received a call from Neha Yadav again saying that the Sapient project is on hold and I'll try to find another project for you and disconnected the call. Seriously? Is this the way to treat a candidate? I don't know what will happen using my documents. I'm another disappointed victim. For NLB services, this is just another day for their criminal activity.
