I have no info about whether Google/Facebook programmers can solve whiteboard questions easily so I expect this comment to be down voted but ... I'm consistently surprised by the fact that, despite hiring programmers who are the world's most elite, Google's products and services are just kind of ... plain/average/boring. The products and services are far less amazing than Google's engineers. It's like Google takes in geniuses but outputs kind of boring, standard, average quality products and services with a surprising number of problems and deficiencies.
