HCLTech .NET Support interview questions

We were called in person in a walk-in kind of setup. There were roughly 7-8 other people for same profile. Despite being there in-person all of the rounds were telephonic. There were two rounds, 1st technical over the phone, second Senior manager and a mix of situational plus technical. After that there was an HR round for salary discussion. I was informed that I've been selected and wait for offer letter. After few days got an email to send all documents, salary slips etc but then no offer letter was released by this fraud organization. It was all a waste of time and seems like fake recruitment drive was held.
