> good strategy makes you ready for whatever luck happens

Yes, I agree that attempting to schedule things in this manner is better than not, should you find yourself able to do so. But, I don't agree with the parent comment that it is "the ultimate and most powerful interviewing technique". Scheduling by preference is moot if (1) you don't have a resume/background that lands interviews in the first place and (2) you don't have the chops to be successful in technical rounds.
