Cognizant — no response from the company regarding the offer letter

Address: Bangalore, Karnataka

This complaint is on behalf of my friend. My friend was interviewed at Manyata Tech Park On 21st July 2018. She cleared technical interview as well as HR interview and got a mail regarding the background check mentioning that they will let her know the status after 2 weeks. It has been almost a month now and they have not yet responded. The most frustrating part is that they don't reply to the mail sent by her. Please look into this matter. It is very unprofessional behaviour by the company with such name and fame
