Initially, their HR guy from the company got in touch and after getting all details, kept sending mails that they are processing. After 22 days suddenly arranged for interviews and after 2 rounds (with Manager and Group Manager) he told me that everything is cleared and will discuss package. He asked me to resign from the current company and he's releasing the offer letter. The next day onwards this person went absconding, gave no response to calls/messages. Such fraud, irresponsible, and careless HR should never be believed.
