The process took 3 days. I interviewed at Meta in Jun 2011
Interview
The phone interview was basically a run down of my previous experience, and me demonstrating my knowledge of the company. These guys put a lot of emphasis on prior knowledge of the company, which might be fair given that I was interviewing for a marketing data analyst position.
The process took 3 weeks. I interviewed at Meta (San Francisco, CA) in Apr 2010
Interview
It's a tough company to get in. I had to do a recruiter screen, another phone screen with a team member, one in house with 3 team members, and another in house with 2 team members - including the director of the group. Mostly behavior with a few analytical situational questions.
The process took 4 weeks. I interviewed at Meta (Palo Alto, CA) in Aug 2010
Interview
I submitted my resume on their website and heard back from HR about 2 weeks later. There were two phone interviews and a 2 hour onsite interview. All communication following their initial contact with me was very prompt, and phone interviews were all on time. Everyone I interacted with was very helpful and pleasant, and as I was coming from Google we had a lot in common. I think having Google on my resume was what helped me get a response, as I didn't have much relevant experience (I'm a recent college grad).
