I am trying my best to give useful feedback following interviews.
But sometimes I really struggle to say anything helpful around a poor fit. I don't want to offend anyone by straight-up saying "You were so annoying you would do everyone's head in and no one will want to collaborate with you" but that is what I would say if I was being honest.
As a recent example: Incredible candidate for a marketing role on paper. It is a new role for us and we are a small team of 35. In a 30-minute phone call, they were constantly talking over me, went on strange tangents, kept talking as though we were a marketing agency and did not respect the time limit I had booked the call for. Whilst they may have had the skills, I would be too concerned about how they would work with other people.
How can I advise a candidate like this I will not be processing their application in a fair but helpful way? Rather than a generic "other better candidates" response.
In the past, I have given the benefit of doubt to candidates like this and invited them in. But the line manager for this role trusts me and would rather not see them!
