I was first contacted by an HR Rep from HQ in Cleveland. The position itself was located in Indianapolis. The interviewer came off very rude and curt about my previous experience. He snickered when he asked about a recent layoff and asked me what happened there. I've been through many interviews and was left with a negative impression.
I was asked for an onsite interview and despite our difficult schedules, we were able to have one. The interview was basic previous experience questions until the second interviewer joined. During this portion he asked me several unprofessional questions including asking me if I was married (I am a young female) which made me very uncomfortable. Not only does that open them to potential lawsuits its just not necessary to ask a female applicant if she is married. He then asked me if I "moved up here all by myself" which I found condescending and odd. I don't know if this was their way of trying to see if I was a single mom with children or what exactly the end game was. Through out the line of questioning I was basically forced to divulge a lot more information about my private life than I feel an interviewer should know. If an offer was made to me, I would decline.
Bottom line, if any of your employees are interviewing potential applicants I STRONGLY suggest giving them additional HR training or having a rep present.
