These guys got my contact details from some indian job portal.

They made me to do a web application and made me to attend multiple rounds of interviews and sent me a kind of offer letter(the letter even contains the salary) for a client in Dubai.
One of their associate from dubai(Seems to be a senior guy) even said me to resign from my present organization.

For God's sake I didn't do that.
It's been a year now. There wasn't any reply after that. Sent multiple mail seeking the status. Initial days I used to call the guy, and he used to tell me to wait wait wait...
