The interview process is both demanding and rewarding and you get as much out of it as you put in it. It consists of five steps, out of which the major and most demanding steps are researching the facebook product and doing the sales demo. There are no special tricks to the process, just be yourself, do the work, and don't try to bs. As mentioned in multiple interviews here, they allow you to ask questions and probe into the role and company a lot, and I recommend using it to your advantage.

- Phone screen with recruiter, then hiring manager. - Technical puzzle. - Interview that tests on facebook advertising concepts. - 'Selling' the team their own product. - Discussion with leadership. The process was challenging and over a period of almost 3 months, with hours of preparation needed for steps in between. The reasons for each step is well explained and the interviewee is also made to learn a lot about the product and facebook advertising. Feedback is given at every step which was great. What wasn't great was business needs changing after the 3 months of interview that the demands of the role were no longer met and this resulted in a no offer despite good feedback throughout. Future interviewees are advised to be more ambiguous with your career goals as this might also be used as a reason for rejection.
