10 Meta Software Engineer (New Grad) Interview Questions (2026)
Meta's E3 new-grad SWE loop in 2026 is a recruiter screen, one or two technical phone screens, and a full-day virtual onsite of two coding rounds and one behavioral (Jedi) round. Coding rounds favor common LeetCode patterns from a curated tag set, with a strong preference for speed and clean code.

Loop overview
New-grad E3 candidates report a 3-5 week timeline from screen to offer in 2026. Phone screen is 45 minutes with two coding problems back to back. Onsite is two coding rounds (35 minutes each, two problems per round) and one Jedi behavioral round. New-grad does not get a system design round. Bootcamp team-match happens after offer signing.
Behavioral (4)
Tell me about a time you received critical feedback. How did you respond?
Frequently askedOutline
STAR: Situation (context) → Task (what you needed to do with the feedback) → Action (how you took it in, validated it, changed your approach) → Result (what improved). Show coachability. Avoid feedback that ends with 'and they were wrong about me.'
Why Meta? What about working here motivates you?
Frequently askedOutline
Pick a specific Meta product, Reality Labs project, or engineering culture trait (move fast, focus on impact). Avoid generic praise. Tie it to a concrete experience you have had as a user or developer.
Tell me about the most impactful project you have worked on.
Frequently askedOutline
Pick one project. Define impact in measurable terms (users helped, latency reduced, errors prevented). Be honest about YOUR contribution versus the team's. Meta optimizes for impact — show you understand what 'impact' means.
How do you handle disagreement with your manager or tech lead?
Occasionally askedOutline
Show you can disagree respectfully and commit once a decision is made. Walk through a concrete example. End with what you learned about communication or the technical area. Meta values speaking up but also commitment after the decision.
Coding (LeetCode patterns) (5)
Given an array of integers and a target, return the indices of two numbers that add up to the target.
Frequently askedOutline
Hash map of value to index, single pass. O(n) time, O(n) space. Clarify: can the same element be used twice? Is there always exactly one solution? Be ready for follow-up: three-sum, four-sum, sum closest to target.
Given a binary tree, return its vertical order traversal.
Frequently askedOutline
BFS with column index per node (root = 0, left = -1, right = +1). Group by column in a hash map, sort by column at the end. Discuss tie-breaking when same row, same column. O(n log n) time due to sort.
Validate that a given binary tree is a valid binary search tree.
Frequently askedOutline
Recurse with min/max bounds. Pass bounds down, return false on violation. Alternative: in-order traversal must be strictly increasing. Discuss why naive 'left child smaller, right child larger' check fails on grandchildren.
Given a string, find all anagrams of a pattern p within s. Return start indices.
Frequently askedOutline
Sliding window of size len(p) over s, comparing character frequency. Use two arrays of size 26 (assuming lowercase) and a match counter. O(n) time. Walk through the increment/decrement carefully — this is where candidates bug out.
Given a list of intervals, merge all overlapping intervals.
Frequently askedOutline
Sort by start time. Walk the list, extending the current interval if the next start is within current end, otherwise push current and start a new one. O(n log n) time due to sort. Edge cases: empty list, single interval, fully contained intervals.
Technical (1)
Given a sorted matrix where each row and column is sorted, find a target value.
Occasionally askedOutline
Start at top-right corner. If current is target, return. If current > target, move left. If current < target, move down. O(m+n) time, O(1) space. Discuss why binary searching each row is suboptimal.
Meta interview tips
- Phone screens are two problems in 45 minutes. Pace matters more than at most other companies. If you spend more than 18 minutes on the first one, you are behind.
- Coding answers should be clean enough to merge. Variable names, no dead code, runs on the first try if possible. Meta cares about code hygiene more than most.
- The Jedi round is a single dedicated behavioral. Prepare four to six stories that you can map to different prompts (impact, conflict, ambiguity, failure, fast learning).
- Meta has a published list of the top 50 LeetCode questions they ask. The signal is that the hit rate is high. Treat it as a confirmed pattern map, not an exhaustive list.
- New-grad E3 candidates do not get a system design round. After offer signing you go through bootcamp and team match — that is where team-specific fit is evaluated.
Frequently asked questions
How long is Meta's SWE new-grad interview process in 2026?
Most reports show 3-5 weeks from phone screen to offer. Bootcamp and team match add another 6 weeks after offer signing.
Does Meta give new-grads a system design round?
No. E3 new-grad loops are coding plus behavioral only. System design starts at E4 (mid-level) and becomes a full round at E5.
How many coding problems does Meta ask per round?
Two problems per 35-45 minute coding round is typical. Phone screens are two problems back to back. Onsite has two coding rounds, so candidates solve roughly four coding problems on the day.
What is the Jedi round at Meta?
It is the dedicated behavioral round. Named internally as 'Jedi.' Focuses on the candidate's prior work, conflict handling, ambiguity, and alignment with Meta's values (impact, ownership, speed).
Does Meta publish its interview questions?
Meta publishes a top-50 LeetCode-style list as part of its prep guide. The list signals high-frequency patterns; the actual interview problems may be variants of those.

HireVue Tech Interview Guide: The 2026 Playbook for Async Video Rounds
HireVue is the category-leading async video interview platform. Candidates record answers solo, on the clock, and a combined AI-plus-human review layer scores the recording days later. For 2026 tech jobseekers, the format is different enough from live interviews to need its own playbook. This guide is that playbook.
CodeSignal GCA for Tech Interviews in 2026: The Complete Guide
The CodeSignal General Coding Assessment is a 70-minute, four-task timed test scored on a 600 to 850 scale, used as a filter by Goldman Sachs, Capital One, Robinhood, Brex, and a growing list of tech and finance employers. This guide breaks down what it tests, how it scores, what it tracks during your session, and how a modern desktop setup pairs with it without showing up in proctored recordings.
CoderPad Live Coding Interview Guide (2026): What the Pad Tracks and How to Walk Through It Cleanly
CoderPad is the default live-coding environment for human-led technical interviews in 2026. Used by YC startups, FAANG-tier teams, and most of the tech mid-market. The pad records every keystroke, every paste event, every language switch, and offers an interviewer scrub-back feature most candidates never realize exists. This is what CoderPad tracks, how the live session compares to async assessments, and how a modern desktop AI setup pairs with it without showing up in the screen-share.
