The interview process was very extensive. A phone interview lasted about 40 minutes; An all-day extensive interview was conducted with 5 parts. A follow-up interview was then conducted with the VP who manages the entire PMO and shared services.
The all day interview had the following sections: Part 1 is a 2-part (100 min.) computer multiple choice and scenario/answer kind of tests, one for personalities, the other similar to GMAT for analytical / MBA type of questions. Part 2 is 1 hour with hiring director 1:1. Part 3 was an informal lunch interview with two directors, but they don't waste time, and many personality and work history related questions were asked, and they certainly assess interaction and reaction beyond office environment. Part 4 was a quick one-on-one with a peer senior project manager. Part 5 is a case study of a past nation wide implementation project, followed by a presentation to an interview panel consist of 2 directors and 2 peer senior project managers. The cases were created by two of the interviewers, and they ask for how would you do it, similarly or differently. Be careful criticizing what's shown on the case written - you may offend some of the interviewers.
Overall, the interviewing process is good, and if your experience and knowledge excel, you have a good chance. However, the flaw in the process is, interview panelist may not value different management methodology when the case study was to analyze and critique on the project they managed in the past. The panel does not have any representative from stakeholders such as management from customers or technology side. Personality assessment from face-to-face interview was also limited to feedback from peer or supervisor, but not from departments where a senior PM will truly interact with.
