What I was trying to say that lot have been said about hiring metrics and standards around here and elsewhere. Yet, at the end of the day still like arbitrary in both ends and makes the job transaction cost higher than what could possible be.
Anyways, as I read your company’s interview process. Something came to my mind, why not let the candidate decide which questions to pick? I say so because I find the a lot of interviews are so hit or miss but if I was given a bit of control over the process, things could be different (or at least I would like to think this way).
