We are recruiting a part time nanny. We have interviewed four women and now have whittled it down to a favourite and a second favourite. Our favourite is not sure about taking the job because of her long commute (30 mins drive, one way, for a four-hour long job). She will come for a trial day next week anyway.
My question is, should we invite our second favourite candidate for a trial, now? Is it usual to trial two nannies? I'm also a bit worried that, for the second preferred candidate, it makes us look bad that we are not going to be contacting her for at least another four days after the interview. It may become obvious to her that she is not our preferred candidate.
