> With the plethora of prep material available for past several years, the bar for interviewing has just moved higher and higher at good companies. If you look at G and F (and some others), there is no way you can get away with just knowing the basics of trees and binary searches. It just takes time.

This is so idiotic. Asking about binary searches does not identify good candidates unless they're going to be doing a lot of binary searches.

If someone asks me stupid CS 101 questions in an interview it's a red flag to me.
