I had a similar experience - from first phone call, to last (rejection) phone call was about 4 months. Their actual interview process wasn't bad however. They never asked me any trick/puzzle questions. Everything was based on coding, algorithms and designs. 4 months, however, is inexcusable. If I was actively looking for a job at the time I would have given up on google long before they got back to me.
