While we dint exactly hire but we had an even worse situation. A particular developer from our team was conducting "real time" training outside office. He referred two guys for a particular job opening. While interviewing the first guy, in-person interview, we asked about process flows at his last job. The answer was uncannily similar to what we were doing. We were intrigued and dug deeper. It became apparent to us that he was describing our process back to us. When we asked about what OS his current employer was using for prod systems, he folded. So, we ended the interview. The 2nd guy, again in-person interview, repeated the same process flow. And he came prepared. He said the prod systems were Windows. When we pushed about the Windows flavor he answered Windows 10. He had never heard of the server version of Windows like 2012 R2. The best part was that he somehow thought the job was already in the bag. So whenever we asked a difficult questions his answers were pretty passive aggressive. Though I complained to both HR and developer's US manager, nothing came out of it. All reports were ignored.
