Agreed.
> But white boarding is excellent for answering all those questions.
I disagree. There is no team social dynamic in a white-board interview. There is one person in a position of power who is judging you with a critical eye. The other person is being judged and either really wants this job or, worse, needs the job.
That is the social dynamic in the room.
That doesn't go away by saying "Let's play pretend like we are working on a project as equals".
Interviewers will often discuss their rationale as if the candidates know what it is, or that they should be able to know it.
For instance, "I want to see if they can take suggestions and run with it".
Great, how does the candidate know that's what you want? Maybe the last interview they were in wanted to see if they could take bad advice and quickly explain why that strategy wouldn't work.
Those both look the same from a candidate's point of view. They need to toss the dice and assume they interpret your intentions clearly.
> Being willing to jump through hoops means you're willing to cooperate and go the extra mile
I don't know if I fully agree, but working at a big company does involve a lot of hoop jumping in your day-to-day, so I guess it is something good to test for.
