I have limited experience in these matters, but have to say that my assesment day with flyBe showed them to be polite, considerate and thoughtful people. Sure, they have a job to do and it must be hard work seeing a group of 15-20 people days at time.
Airlines have to recognise that their assesment day sets the tone for how crew/wannabe's judge them. After all, we all talk about the good airlines and the....ahem, not so good airlines.
PS Pandora's Box - your post made me laugh. Lets face it, he's only got one aircraft to recruit for - must be a HUGE challenge for him.
