If the tweet is accurate in its implication that he didn't get hired because he couldn't invert a binary tree (honestly, I don't even know what that means) on a whiteboard, then I'd say the tweet is totally justified.
On the other hand, if it was a complex and reasoned decision that he's summarizing badly, then yeah, good call on their part.
Context is king here, and we have little.
Slightly off-topic but I always found it infuriating to call binary trees "binary" when some vertices have a degree = 3. :P
If you can make a convincing case at the whiteboard, maybe Google will hire you!
