Someone at Uber reached out to me about a role there.

First step of the interview was a phone screen. It was high-level and conceptual, and given by an early tech employee who wasn't HR but, at this point, wasn't entirely a hands-on tech person either. They had moved into more of a director/operations role.

It asked some basic tech questions, but I don't think the person was expert enough in iOS itself to ask difficult questions.

Next was an at-home coding challenge. Take as much time as you want, but the expectation was within a few days to a long weekend. I completed it over an entire weekend and put substantial work into it. It was a straightforward iOS question with an API and UI elements. I put a lot of work into it.

After reviewing the submitted challenge for a few hours, I received word back that there was a flaw in a UI element, and we would not be moving forward. But they thanked me for spending my entire weekend on it. There was no discussion, no further communication.

After further investigation, I confirmed my flaw. A little frustrated because it clearly showed I was adept and could do the work with overall nice features, but also not happy with myself for my mistake that I didn't initially see in the UI.
