After applying and sending my CV through Facebook website, I had 2 phone interviews - first with the recruiter, then with the SMB team manager. The recruiter was very helpful, giving feedback after each of the interviews and helping prepare for the next one. Then I got invited to Dublin for an on-site interview at Facebook office, where I was interviewed by three people in the space of 1.5 hour - team manager, marketing manager and SMB director. The first two were very nice, while the director seemed rather unpleasant and absent-minded, but maybe that was his interview strategy. The whole process was very nice and clear, but I did not get the job, as I did not have enough sales experience.
