I applied online. The process took 3 months. I interviewed at IDEO (Palo Alto, CA) in Jun 2013
Interview
I had an initial phone interview with HR, then a Google Hangout interview that went well and lasted about 1.5 hours. Shortly after, I was notified they wanted to fly me out for in-person interviews. This lasted about half a day, and ranged from discussions with senior management to an ideation session with a team of designers. I was told a decision would be made hopefully within a week. Within a couple days, HR told me that my interviews "went really well". Over 2 months went by. Eventually I received a very nice letter stating they weren't going to move forward with my application, that the applications had been extremely competitive with many qualified candidates and the selection had been difficult. Two weeks later I saw the posting listed again on a job board.
Interview questions [1]
Question 1
The ideation session was probably the most difficult part of the interviews, only because you are working with a team of people, none of whom you know. But it was not a problem.
I applied through an employee referral. The process took 5 months. I interviewed at IDEO (San Francisco, CA) in Apr 2013
Interview
I spoke with 2 HR people two separate times, then spoke with a designer and then spoke with two directors designers. The process was very casual. I had to go through a couple of projects- show process, results, and next stages. The interviews were very spaced out. It was very difficult to tell what they were thinking. Everything seemed to go well but in the end didn't land the job. Got a nice letter telling me to apply in the future 6 months to year.
