Religiously study the job description and reflect it with the experience you have. My advice would be to really get a hold of the recruiter during the initial stages and ask them about the skill-set the hiring team (and the manager) is looking for. Note those down and prepare to reflect those skills in the interview questions that will be asked. You'll most likely encounter questions that are already floating around here and in that case Google and Glassdoor will be your best friends! Search for as many Facebook interview questions (related to the position or at least close to what the position is) as you can and prepare notes and examples. This will also put you in the right mindset to answer questions tricky questions that can come up.
