I was contacted by an external recruiter on LinkedIn.

I then went on a phone screening interview with a recruiter who works for Yelp.

The recruiter called me late and was not very polite. He seemed unconcerned about what I was saying, even when I was describing my career so far.

He then asked me some small iOS, data structures, and web-related questions.

I was told that I would be having a technical interview with one of their iOS engineers via Skype a couple of days later.

The interview started with me describing my current job and asking questions about how they work at Yelp. I then had to answer some questions about memory management in iOS.

The second part was a coding exercise on Coderpad.io. The question was to find the anagrams of a word from a given array of words.

While the interviewer was explaining the problem's requirements, I started hearing chat sounds, as if someone was writing to him. He then began responding to them and even laughing at times. He told me they were sending him funny messages, so he removed the audio.

This made it impossible to ask him questions while I was trying to solve the problem. I initially solved it with a naive approach, which had a very high complexity. I then devised a better solution, but I think I took too much time to arrive at it.

A week later, the external recruiter contacted me saying I didn't pass, but offered no feedback.
