Apologies for this dumb question, but I'm new to The Apprentice this series.

Firstly, what IS the interview stage? Is It the final 2? And what's all this about people being "taken apart" at this stage? I'm so confused now

After the next two tasks the five remaining candidates will all be interviewed by some more of Sugar's trusted advisers.

They will then report their findings to him and he will ignore them and go with his already formed opinions.

It can be quite fun when someone who has an unpleasant aspect to their character finally gets their comeuppance. (This is what the reference to 'taken apart' is referring to.)

On the whole, though, I'm not that keen on them because there is a definite 'bullying' aspect from some of the interviewers.

he 'taken apart' thing refers to the way that quite a few of our confident, egotistical candidates seem to collapse under the weight of their own lies when probed about their achievements and CV's!

Its the bit where only Helen is revealed as remotely winnable

Ah okay, I understand better now. Thank you
