This is so wrong that it actually hurts my brain. Albert Einstein, a certifiable genius probably could not tell you how to invert a binary tree, this has nothing to do with intelligence and everything to do with how many HackerRank problems you have memorized.
- recursive 8y agoThere are many things you can do with a whiteboard other than inverting binary trees. You're thinking too narrowly.
- nunya213 8y agoObviously, but I was specifically referring to the typical algorithm oriented whiteboard questions found at major tech company interviews. Working a real world problem on a whiteboard I see no issue with.
- recursive 8y agoThis whole post is about companies that "don't whiteboard". Not companies that "only whiteboard for real world problems".
- Melchizedek 8y agoTrue, but there are also brain-teaser type problems that don't require memorization of obscure algorithms, and those could actually be disguised intelligence tests. (But I suppose if you really wanted to you could memorize most of the brain-teaser problems in existence.)
- nunya213 8y agoGoogle has already shown that those types of questions have 0 correlation to developer success.
- Grue3 8y agoWhat's so hard about inverting a binary tree anyway? If Einstein lived today and was into computer science, he'd be able do this in his sleep.
