I had attended an online interview for a post of team lead. I had informed them earlier itself that I am undergraduate. But they informed that it's okay and can hire me if I clear the interview. I cleared the interview and the HR advised that it will take some time as I do not have graduation and my job is confirmed. I asked the HR to send a mail confirmation stating the same , which the HR sent. As I had a job, I rejected the other offers that I had. But now the HR states due to company policies, they cannot hire me. As I have lost all the offers that I had believing in the mail confirmation from the company's HR. Is there anything that i can for the time that is been wasted by the company and for the stress I would have looking for another job???
