There were multiple rounds with a number of different departments, including Product, Engineering, and Project Management. There were also many sessions in one day or throughout the week, so you would need to block off a chunk of your day to get through each 30 minute session with different interviewers. I did have one issue where the HR person did not add me to one interview, but added the interviewers, so I ended up almost missing one of the sessions, but it was clearly not my mistake so it worked out.

Took about a month between the first time the recruiter communicated of the hiring manager's interest in my resume and the phone interview. First a generic description of my background and walked through my work experience, The manager then described the group and products including the one I was interviewing for in terms of the challenges and my brief experience with the product. The interview seemed to have convinced the interviewer of my strategy approaches to get through the hurdle, but the manager was reluctant to continue talking with me based on my extended period of unemployment.
