Hitachi provided an offer to the candidate in the morning and he took time to accept the same. HR team called him in the afternoon and he was not aware of this due to some situations

HR team member sent a mail to the candidate mentioning the below:
"We have been trying to reach you for the past 5 hours and you have not responded. Your profile will be uploaded on the blacklisting portal if there is no response before EOD"

This type of behavior is not expected from a reputed company. Company didn't understand the situation of candidate and sends messages by blackmail a candidate in the name of Blacklisting which is inappropriate.

Hence i am raising this complaint against unethical behavior of the company
