Luckily, Business Insider recently spoke to Facebook global head of recruiting Miranda Kalinowski and VP of people Lori Goler to get a better sense of what it's like to interview at the Menlo Park, California-based company. Kalinowski notes that the process can vary based on what team you're being hired onto.

But across the board, she stresses that Facebook recruits individuals through a number of different channels, including the company's careers sitejob fairs at universities, conferences, and even TED Talks. Generally, recruiters will first screen you over the phone to cover some basics and make sure you're a real candidate. After that, Kalinowski says that recruiters hand over the hiring process to employees who might be working with you directly.

If you show promise, then you'll be invited to visit Facebook to check out the campus and go through four to six more interviews with some of your potential team members. Goler says that, ultimately, Facebook is looking to place people in positions that play to their strengths, and she has some simple advice for anyone who wants to work at the company:.

Although Jane seems both interesting and pleasant, she is still unfamiliar to me, and this put me out of my comfort zone. Then this discomfort was enhanced by the camera, the assignment, and my self-conscienceness. As stated, this assignment made me surprisingly nervous.

However, the awareness that I might be blowing it made me more nervous, so when my nose started to itch right after the camera went on, I had a meltdown. Once the interview started, I was concerned about the time, and also about having the next question ready.

But I was aware of it at the time. On the plus side, I thought my questions were good and they worked well in the flow of information. I had prepared a strong list of main questions, with multiple follow-ups to anticipated replies to those main questions. I only used some of the follow-ups, depending on how Jane had answered.

This strategy worked well, and I got the information from Jane that I wanted. Plus, I thought it seemed fairly natural. We covered the bases I was trying to address. I also think I had empathy; I showed some emotion, and it was appropriate for the discussion. I had voice inflection, and I smiled. I think I put Jane at ease.
