The HR recruiter reached out to me via email and asked me to apply online for their position.

We scheduled time to speak. The recruiter was pleasant.

I was scheduled for a technical screen where I was told I would be asked architecture and mobile-related questions. I was first asked a few questions about my background. I was then asked a mild algorithm question, and the interviewer at least tried to be somewhat helpful throughout (though he was not helpful and was very rude).

I did my best to answer the question. At the end of the interview, he asked me to ask questions. I asked him a few, none of which he answered, but he quickly gave sarcastic responses and seemed uninterested in responding.

Thanks for wasting my time.

Typical HR questions. I was asked an algorithm question in the tech round after being told it would only be iOS-related architecture questions.
