I agree. I've interviewed loads of people, without ever giving a job to someone who couldn't do the work.

I just have a deep technical conversation. If they run out of things to say, they are not right for the job. They run out of BS, because I keep the conversation on specific things that you can't make up, yet keep it open enough that you have to bring your own experience.

That's it, (spoiler alert!) it's like the great reveal in Kung Fu Panda.

This is the guy you find with this method. He can talk forever, because he loves what he does and can't not keep doing it.
