The interview process involved a preliminary but lengthy phone call with the hiring manager (nearly 1.5 hours). This was followed by a request for a sit down interview. Prior to that interview, I was to submit a product development plan as a test of my background for the position. (Note that I generally frown on the delivery of product ideas or proposal as part of any interview. Technically any such written material is the property of the interviewee. This kind of request is easily subject to abuse--amounting to little more than theft if the proposed ideas are used. I took a chance in engaging with this process because of special circumstances: I was returning to a company for which I once worked so I was familiar with and trusted the participants.) After submission and sit down, I waited a period of about 3-4 weeks before receiving a formal offer. Otherwise the interview was a straightforward process of meeting in one of the company office's and walking the interviewers (there were two) through the research process and my prior experience in the development of projects similar to that I was presenting.
