Applico Software Engineer, Mobile interview questions

Arranged the interview over email. Interviewer was 20 minutes late and visibly stressed. Moody and uninviting (even took a crack at my name). The technical questions were trivial and involved knowing specific object hierarchies. For the one open ended question he asked me, he didn't like my answer but couldn't verbalize exactly why. Took my information for a second interview but haven't heard back. Hands down the worst interview I have ever sat through.
