Stop wasting people's time. If you say you'll let the candidate know about result of interview in 15 working days, then let them know in 15 working days. I travelled all the way to Dhaka for interview. The interviewer was sleepy and totally uninterested. He said they'll let me know in 15 working days and then they ghosted me. I tried emailing the hr, turned out the email address doesn't exist. Tried calling the hr, turned out she doesn't work for Polygon Technology. STOP SCAMMING CANDIDATES. Their time has value.
