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 pretty pleasant. I was scheduled to do 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 guy at least TRIED to be somewhat helpful throughout (he wasn't helpful at all though and was very rude) I did my best to answer the question. At the end of the interview he asked ME to ask questions and I asked him a few questions, none of which he answered but just quickly gave sarcastic responses and seemed uninterested in responding to. Thanks for wasting my time.
