Half way through a recent interview it became very apparent that the candidate was using AI. This was only apparent in the standard 'why are you interested in working here?' Questions. Once the questions became more AI resistant the candidate floundered. There English language skills and there general reasoning declined catastrophically. These question had originally been introduced to see see how good the candidate was at thinking abstractly. Example: 'what is your creative philosophy?'
> Have you noticed a correlation in candidate quality vs the time spent answering that question?
Yes, certainly.
Over the years our skill at interviewing has grown. We try to craft a balance between asking questions which require exact responses, and those which the candidate is free to improvise upon.
