First an HR screening with a few standard questions: -Talk to me about previous experiences -Why you want to work at uber -Question in English Second round was an CodeSignal Question with screen sharing. The question gave two strings, one was a word like "axubbxcxbxd" the other was a character order, like "abcd". They asked to return true or false whether the word followed the character order. So in this example would be false because there is a substring "cxb" which would violate the order (b < c).
