Shutterfly Director - Marketing interview questions

18 interviews in total via phone, Skype and in person in Redwood City, CA.

The initial contacts with HR went well - I got scheduled promptly for a phone interview, which was followed by two separate Skype calls a week later. Then I received an invitation to fly out to CA to meet with 7 people over the course of 5 hours. So far, so good. Sent thank you notes to everyone within 20 hours, including the HR coordinator. Sent follow-up note to the hiring manager and her boss a week later. Sent a reminder to the HR recruiter a week later. And another one a week later. After 3 weeks, I still have not heard from them about a decision. Only some excuses from HR about how busy everybody is. Apparently they came to the conclusion that I'm not the right candidate for this role, but I was disappointed to receive no communication about that decision. And for a senior role like this, after such an extensive process, I expected some feedback as to why I'm not the right person for the job.
