First phone interview was 45 minutes. We went slightly over time as my interviewer called late. I was asked questions about my work experience and data structures questions (solutions involved hash tables and trees). I was scheduled for a 2nd interview one week later. The second interview was more impersonal (no questions about my resume) and I struggled to finish the question he presented within the 45 minutes. My interviewer was kind and said I had done well. I followed up a week later, and finally heard after two weeks that I hadn't been selected to interview further.
