Remarks at interviews can easily be misunderstood. A few years ago, A colleague and I were interviewing candidates for an office job. It was a hot day, there was no air conditioning. One candidate looked uncomfortably hot so I suggested that it would be in order to remove her jacket if she so wished. This was later reported back in a letter to the MD., that I had asked her to take her top off!
I am not sure if she was seriously offended by my remark or it was a mischevious attempt to cause trouble because she did not get the job. Luckily my colleague who was present came to my defence, although quite how I would have coped with the accusation had I been conducting the interview alone, I am not quite sure.
