TaskRabbit Head of European Customer Support Operations interview questions

1 recruiter interview, 1 hiring manager interview. Then 6 interviews lasting 30 mins each with various people in London in the US and a 45 minute presentation to 3 of the panel. After 8 days I received a generic email saying other applicants were more experienced. As 6 people interviewed me and I prepared a presenatation which I spent 5-6 hours preparing, I requested more constructive and personalised feedback. I didn't receive anymore feedback.
