Frequently Asked Questions

How hard is the Meta interview?
Meta interviews are considered hard, primarily due to the coding speed required. You must solve 2 problems in 45 minutes (about 20 minutes each). The system design round also requires designing for billions of users. With 4-6 weeks of focused LeetCode practice, most well-prepared candidates feel confident.
What is the Meta interview process?
Meta's process consists of a recruiter screen, 2 coding interviews (each with 2 problems), and a combined system design + behavioral round. The entire on-site is typically 4 rounds in one day. Meta hiring is team-agnostic — you interview for a general role and team-match after receiving an offer.
Does Meta hire for specific teams?
No. Meta uses a general hiring approach where you interview for a level (E3, E4, E5, etc.) rather than a specific team. After receiving an offer, you go through a "team selection" phase where you meet with multiple teams and choose your preferred one.
What salary can I expect at Meta?
Meta is known for top-of-market compensation. E4 (mid-level) total compensation is typically $250K-$350K. E5 (senior) ranges from $350K-$500K+. Base salaries range from $150K-$270K, with significant RSU grants and annual refreshers.
