Meta Software Engineer Interview Questions & Preparation
Quick answer
A Meta Software Engineer interview combines Meta's 4-stage process — recruiter screen, technical screen, onsite loop, debrief & team match — with the technical and behavioural bar for a Software Engineer. Expect Meta to assess move fast and be bold, alongside core software engineer skills like data structures & algorithms and system design. Prepare software engineer answers framed around what Meta specifically looks for.
How Meta interviews Software Engineers
Meta's culture centres on impact, speed and openness. Interviews reflect that: coding rounds are time-boxed and fast-paced, and behavioural rounds explore how you drive impact and work with others. Product and design roles weight execution and product sense heavily.
For a Software Engineer specifically, Meta pairs its standard assessment with a technical bar focused on data structures & algorithms, system design, a core language (e.g. python, java, go). Software engineering interviews test three things: can you code cleanly under time pressure, can you design systems that scale, and can you work in a team. The bar rises with seniority — juniors focus on coding fundamentals, while senior and staff candidates spend more time on architecture and influence.
The Meta interview process
| Stage | What to expect |
|---|---|
| Recruiter screen | Background, motivation and logistics. |
| Technical screen | Two coding problems in ~45 minutes — speed and correctness both count. |
| Onsite loop | Two coding rounds, a system/product design round, and a behavioural (Jedi) round. |
| Debrief & team match | Panel debrief, then matching to a specific team. |
What Meta assesses
Software Engineer questions at Meta
Expect a blend of Meta's signature questions and core software engineer questions:
- 1Solve two medium coding problems in 45 minutes.
- 2Design Facebook's news feed ranking system.
- 3Tell me about a project where you had the most impact.
- 4Reverse a linked list and explain your approach.
- 5Design a URL shortener — walk me through the data model and scaling.
- 6Tell me about a time you disagreed with a technical decision.
- 7How would you find the first non-repeating character in a string?
- 8Describe a system you built end to end and the trade-offs you made.
- 9How do you approach debugging a production incident?
Example STAR answer
Example answer to: “Tell me about a time you led a technical project under pressure.”
Skills assessed
How to prepare for a Meta Software Engineer interview
- Practise solving two problems in 45 minutes — pace is part of the test.
- Frame behavioural answers around measurable impact.
- Think out loud — interviewers score your problem-solving process, not just the final answer.
- Clarify the problem and edge cases before you write code.
- Prepare 4–5 STAR stories that show ownership, conflict and impact.
- For system design, start with requirements and scale estimates before drawing boxes.
Software Engineer salary
UK software engineers typically earn £45k–£90k, with senior and big-tech roles reaching £120k+ including equity.
Frequently asked questions
What does the Meta Software Engineer interview process involve?
Meta's process runs through recruiter screen, technical screen, onsite loop, debrief & team match. For a Software Engineer, the technical rounds focus on data structures & algorithms, system design, a core language (e.g. python, java, go), and behavioural rounds assess move fast and be bold.
How fast are Meta coding interviews?
Meta's technical screen typically asks for two medium problems in about 45 minutes, so pace and correctness both matter.
How many coding rounds are in a software engineer interview?
Usually 2–4 coding rounds, plus a system design round for mid-level and above and at least one behavioural round.
What's the best way to prepare for a software engineering interview?
Practise data-structure and algorithm patterns out loud, rehearse system design with real requirements, and prepare STAR stories for the behavioural round.
