A free AI panel interview that questions you in Meta’s style, follows up when an answer is thin, and returns a scored, evidence-backed report — seeded from your own practice history on Wrexa Edge.
The Meta interview, in brief
Meta runs a highly standardized, team-independent software-engineer loop: you interview into a general pipeline and a level (E3/E4/E5), then match to a team after passing. It is known for a fast, algorithm-heavy coding bar (often two problems per round, medium-leaning) and a distinctive behavioural round internally called the "Jedi" round, weighted comparably to coding.
After an optional online assessment and a recruiter screen, candidates take a technical phone screen and then an on-site "full loop" of coding rounds, a system-design / product-architecture round (E4 and above), and the Jedi behavioural round. Written feedback goes to a debrief and hiring committee, and team matching follows.

Coding & DSA topics
System design
Not asked at E3 (new grad), which is calibrated on coding fundamentals. Asked at E4 (mid) and E5 (senior), in two flavours: Product Architecture (a user-facing system such as a news feed, chat, or commenting system — API design, data model, fan-out) or System Design / infra (rate limiter, distributed cache, pub-sub). Candidates are often expected to set their own scale targets.
Behavioural round
The "Jedi" round is weighted comparably to coding and its interviewer often leads the loop. It assesses ~8 signals — proactivity and ownership in ambiguous situations, conflict resolution, perseverance, empathy, growth and self-awareness, communication — mapped to Meta's values (Move Fast, Focus on Long-Term Impact, Build Awesome Things, Be Direct/Respect Colleagues). STAR is accepted; Meta materials sometimes recommend SOAR (Situation-Obstacle-Action-Result).
Representative question categories
Patterns in Meta’s style — not verbatim proprietary questions.
- Trees / BSTs — Vertical-order traversal, lowest common ancestor, build a tree from traversals.
- String parsing with a stack — Validate or minimally fix parentheses; a basic expression calculator.
- Graphs — BFS/DFS shortest path or connected components on a grid or adjacency structure.
- Arrays — Two-pointer / sliding-window problems optimised to O(n) with hashing.
- System / product design (E4+) — Design a real-time commenting / news-feed / chat system, or a rate limiter — set your own scale.
- Jedi behavioural — "A time you moved fast and it caused a problem"; "a genuine conflict with a colleague and how you resolved it".
How to prepare
Do
- Practise solving two medium problems quickly per round — Meta's coding bar is about speed and clean edge-case handling.
- Prepare 6–8 behavioural stories mapped to Meta's values, each with your individual impact at the right level.
- For design (E4+), set your own scale targets when none are given, and reason about fan-out and storage.
- For the Jedi round, bring a genuine conflict with real stakes — interviewers probe for authenticity.
Avoid
- Going slow on the first problem and running out of time for the second.
- Telling "we" stories with no individual contribution in the Jedi round.
- Neglecting the behavioural round — it carries the same weight as coding.
Who can apply
New grads enter at E3, mid-level at E4, senior at E5 — the design and behavioural rounds gate levelling. The loop is team-independent; team matching happens after you pass.
Meta interview FAQ
- What is Meta's "Jedi" interview?
- It is Meta's behavioural round, weighted comparably to the coding rounds. The interviewer (often the loop lead) assesses signals like ownership in ambiguity, conflict resolution, and self-awareness, using STAR or SOAR-structured stories. Bring genuine situations with real stakes.
- Does Meta ask system design for new grads?
- No. New-grad E3 loops are coding and behavioural only. System design / product architecture is asked at E4 (mid) and E5 (senior), where it carries significant weight for levelling.
- How many coding problems does Meta ask per round?
- Typically two medium-leaning problems in a 45-minute coding round, so pace matters — clarify quickly, solve, and move on with clean edge-case handling.
- Is the Meta interview team-specific?
- No — the loop is team-independent. You interview into a general pipeline and a level, then match to a team after passing.
