I was reached out to by a recruiter via email. The recruiter included information about working at Facebook.

The first interview was a phone interview with two LeetCode hard difficulty questions. The interviewer slightly twisted the questions after I solved them.

I heard back within a couple of days and was invited to an onsite University Day. The onsite experience was amazing. The recruiters are really great at what they do.

I had three interviews which all contained coding questions.

• Two of the interviews were purely technical.
• One was 3/4 behavioral, 1/4 technical.

All technical interviews started with a medium difficulty question, then a harder question. Most of the questions I had not heard of before.

I was extremely impressed by the culture, values, office, perks, etc. After interviewing with other "big-4" companies, this was my favorite. You can really tell that the engineers (from at least what I saw) at Facebook are pretty brilliant. They all emphasized to not fall into imposter syndrome.

Use the resources they give you to study.
