SoundCloud Strategy & Operations Associate interview questions

Had a brief phone interview with HR. Week later they asked me to come in for an in-person interview with the hiring manager. Arrived 5 minutes early for the interview, an the head of HR said I was super early. Hiring manager was not prepared for the interview, never reviewed my resume, didn't know it was in-person. Seemed really flustered by my standard interview questions. Lasted 30 minutes, complete wast of time. Never heard back from HR after I emailed a week later.
