I think it doesn't matter if it is consistent for all the candidates. A company can't change to suit every employee. Working for a startup like Youtube is high pressure. You have to be very self-aware and able to work under extreme circumstances. When your app crashes and millions of people are angry, you have to fix it! You can't create a special case scenario for your employees because they need to work in a stress free environment.

Of course that is a simple case, but high stress engagements occur at some point in almost every environment and how the candidate reacts to the high stress is very important, perhaps the most important.

IMO, it is more important for the employee to adapt to the environment than for the environment to adapt to the employee. Every candidate is going to want questions asked a different way. Every candidate is going to want their cube to be a different color -- that's why they are all gray or beige.

My point is, if you want A players on your team, you will be well served to waste as little time as possible on candidates that want you to ask them interview questions the way the candidate wants them asked and focus your attention on candidates that correctly answer the questions how the interviewer wants to ask them.
