I applied through an employee referral. The process took 1+ week. I interviewed at Meta (Menlo Park, CA) in Jan 2014
Interview
Initial contact and screening took place over Facebook messenger. It was a little odd, being the first interview I'd ever had over a chat system. But it at least got me in the door. There was another phone screen after that with a member of the team, then they brought me onsite. I met with 5 people and it lasted most of the day. Some were good solid interviews with real people who liked to have a conversation and get real information. Some were very cold interviews literally read off a script right in front of me without making any eye contact. I was surprised at the range of interviewing skills and styles.
In the end, I was not offered the job. However, I was never actually told "no". I was only told "we're meeting later this week to discuss" or "there are a few more candidates to get through before we make a decision" and "just wait one more week and we'll have more information." They eventually just stopped answering my emails for a status. I got the hint, and probably for the best.
