First, whiteboard interviews were a great selection criteria for about 30 seconds before it became public knowledge that being able to pass them was a ticket to a google salary. Subsequently, they functioned literally at all while under the pressure of literal billions of people knowing that they were the ticket to a google salary. A criteria surviving this second challenge is extremely impressive. To put it another way: I can hire based on open source contributions instead of credentials and interview performance. If google decided tomorrow to start hiring based on open source contributions, then their new criteria would leak on monday, and on tuesday the pull requests queues of every major project would simultaneously splatter like bugs on windshields.
