First, an HR screening with a few standard questions:

• Talk to me about previous experiences.
• Why do you want to work at Uber?
• A question in English.

The second round was a CodeSignal question with screen sharing.

The third round is onsite with several interviews with different teams (algorithms, coding, and system design).

The first stage was an HR screening with a few standard questions:

• Talk to me about previous experiences.
• Why you want to work at Uber.
• A question in English.

The second round was a CodeSignal question with screen sharing. The question involved two strings: one was a word, like "axubbxcxbxd", and the other was a character order, like "abcd". You were asked to return true or false, indicating whether the word followed the character order. In this example, it would be false because there is a substring "cxb" which violates the order (b < c).
