I've been set a pre-interview task - they want me to turn up and talk for 5 mins on how I would do x. The problem is that I wouldn't (do x, that is). I think it is quite fundamentally problematic and I have good reasons to back this up - but I can't say this can I? Or can I? It seems very negative - it would be rejecting their very idea. (and there's history here - I come from a sister organisation and we quite often reject their ideas) I guess I have to come with ways of doing x but point out potential pitfalls?
