I think I got pretty lucky with mine, but it does appear to be the norm.

Got a phone call from Monique to schedule an interview with her, set it up online for a few days afterward. HR interview was right around the time we had scheduled, then she told me to expect up to a month for the technical, and to call her if I didn't hear anything. Almost a full month later I had my technical, then a class date offer the very next day. Maybe I was lucky.
