Looking to land a job at Facebook but don’t know what the process looks like?
I’ve got you covered. In this article, we will look at what goes on in each step of Facebook’s hiring process, two different types of Facebook’s interview questions, and three tips to ace any Facebook interviews. Here are the four steps of the Facebook Interview Process:
Step 1: Pass the resume screening
Step 2: Pass the phone screenings (1-2 rounds)
Step 3: Pass the on-site interviews (4-5 rounds)
Step 4: Pass the hiring committee reviews and get the offer
Facebook’s recruitment process consists of four main parts: resume screening, phone screenings, on-site interviews, and hiring committee reviews. While each part of the hiring process has its own value, the most difficult and decisive parts are phone screenings (1-2 rounds), and on-site interviews (4-5 rounds). These interviews last 45 minutes on average, with overall conversion at around 16%.
Step 1: Pass the resume screening
The first part of Facebook’s hiring process is, similar to most corporate jobs, resume screening. In this round, recruiters will screen your resume for technical requirements, education, experience,.. to make sure you’re a potential fit.
Although hiring criteria depend on roles and company, the fundamental principles of writing winning resumes at Facebook is almost identical to writing winning consulting resumes. There are three fundamental rules you must apply in your resume:
What Facebook looks for in its employees are: leadership ability, analytical problem-solving skills, excellent written and oral communication, “gritty” character, intense curiosity, and humility.
When talking about your experiences and achievements, the way to go is through objective information. A good bullet should sound something like:
“Reduce overhead by 20% (or $2MN) for an online news media company by leading a cross-functional team to migrate the client’s finance operations cost centers to a shared-services model.”
Using professional, structured, and to-the point language implicitly shows screeners that you’re a good communicator. Highlighting your achievements with explicit numbers and good structures also save screening time and leaves a good impression.
Before moving on, I highly recommend you checking out my consulting resume overview and specifically look at the resume examples I corrected to see how these rules can supercharge your resume.
Step 2: Pass the phone screenings (2 rounds)
There are usually two rounds of phone screenings at Facebook : the recruiter phone screening (or the pre-screen) and the technical phone screening.
In the recruiter phone screening round, which lasts 20 minutes, an HR recruiter will contact you to ask a few questions on the phone. These questions are somewhat behavioural, aiming to reveal your background information and qualities, from which the recruiter will assess your fit for the selected role.
If you pass this initial phone screening, the recruiter will match you with a Facebook engineer to conduct the technical phone screening, which lasts around 45 minutes. You’ll be asked some questions pertaining to your resume for 10-15 minutes, then spend the next 30 minutes completing one or two coding questions (e.g. data structures, algorithms, etc) on a simple online code editor (e.g. CoderPad).
Step 3: Pass the on-site interviews (4-5 rounds)
Once you’ve passed the phone screenings, you’ll move on to the tough on-site interviews. In a typical on-site interview, you will be interviewed with another 4-5 people for 45 mins each.
On-site interviews usually consist of 4-5 rounds, in which two things will be assessed: (1) Your fit for the selected role (role-specific fit) and (2) Process, teamwork, and culture fit (firm-specific fit).
For technical roles, there are generally two types of interviews you should be aware of: Coding on-site interviews and System Design on-site interviews. For each type, expect 2 or more interviews.
Coding on-site interviews involve whiteboarding solutions to slightly harder data structures and/or algorithmic problems. The lesser experienced you are, the more number of coding onsite interview rounds for you.
System Design Onsite interviews involve coming up with high level design architectures for real life products. The more experienced you are, the more number of these interviews you might face.
For both technical and non-technical roles, you’ll definitely get teamwork/process/culture fit interviews. The fit interview will be a combination of topics ranging from agile methodology or workflow, teamwork and collaboration, and conflict resolution.
Step 4: Pass the hiring committee reviews and get the offer
Congratulations! You’ve passed the on-site interviews, the toughest part of the interview process. At this point, candidates will be assessed in candidate review meetings, where team leaders/ managers will determine whether you’re a good fit for their respective teams. If a team wants you, they’ll tell your recruiter and it will be added to your portfolio, which will then be submitted to the hiring committee
After that, your performance will be evaluated by a hiring committee consisting of Facebook seniors. This step is usually a formality. Before the hiring committee session, each reviewer often takes hiring recommendations made in the candidate review meetings, which will be discussed during the session. If all members agree on one recommendation, an offer will be extended.
2. Three Tips to Ace Facebook Interviews
The beginning of every interview at Facebook will involve 15-20 minutes of behavioural questions. Hence, it’s crucial that you present yourself in a consistent, thorough manner. Most importantly, however, you must demonstrate the traits that Facebook looks for in every answer. Below, I’ve summarised three tips to help you ace every fit interview question, keep reading!.
Tip 1: Prepare stories, not questions
For any interview, especially fit interviews, it is best to prepare 3-4 detailed, all-round, refined stories exhibiting all the required attributes (for Facebook, they’re the below “Facebook” traits). This way, you can tune the stories according to the interviewer’s questions in a flexible, consistent manner.
Many candidates make the mistake of preparing on a per-question basis, i.e listing out the possible questions and the corresponding answers/stories. Wrapping your head around inflexible answers can throw you off-balance when an unexpected question comes up. The resulting storytelling style is also somewhat robotic.
Instead, in the Case Interview End-to-End Secrets Program, I teach a story-based approach: select a few stories reflecting your best, all-round self, and develop them in detail.
Tip 2: Explicitly show Facebook traits
To prepare your stories, compare your past experiences with Facebook traits, along with personal values you’re most proud of, and select the stories best reflecting those traits and values. You want to show that your values and experiences perfectly match what recruiters look for.
So what are these famous “Facebook” traits? Above all, Facebook places emphasis on kindness, empathy, and humility in their people. Successful candidates also excel in these criteria: learning ability, teamwork, communication skills, leadership.
Learning ability: Facebook not only values excellent cognitive abilities, but also problem-solving ability, curiosity, and ability to learn.
Teamwork: Working at Facebook demands that you’re a great team player. Merely being an independent, hard-working employee isn’t going to cut it – you’ve got to work, think, and succeed in teams.
Communication skills: succeeding in teams also requires excellent communication skills, and this holds true not only for Facebook but many companies.
Leadership: Facebook defines leadership as the willingness to step into a difficult problem and step out when their expertise is not needed. One person is not always going to be the right leader for everything Facebook does – work will be handled in small-sized teams (4-6 people) consisting of people with different skill sets.
Tip 3: Use the Problem-Action-Result framework
As the name suggests, the Problem-Action-Result method, also known as the STAR method, is a technique you can use to clearly demonstrate specific skills/ traits required for a job position. Using this framework instantly makes your answers more structured, logical, easy for listeners to follow, and easy for you to keep track of.
STAR stands for:
Situation: An event, project, or challenge faced
Task: Your responsibilities and assignments for the situation
Action: Steps or procedure taken to relieve or rectify situation
Result: Results of actions taken.
STAR Model Answer:
Last year while working as Customer Service Manager with XYZ Products Ltd in Germany, I successfully implemented a new process which reduced the time taken to process customer refunds from 14 days to 2 days, saving over £100,000 annually in agent time and gaining a 50% uplift in customer approval ratings.
Our customer refund process was taking 14 days and was using up an excessive amount of agent time and resources. I was tasked with reducing this to 2 days with the added benefit of saving time and resources.
First, I initiated the project by clearly defining the objectives and procedures. Then, I created a detailed brief analyzing the problem and outlining the potential benefits of the newly proposed process.
After that, I completed a walk-through of the existing system to identify where the problems lie. I interviewed the agents involved to gather their input into both the current system and their ideas of what they thought would work well.
With all that knowledge, I designed a new process and drafted a brief which I then forwarded to four software companies who specialise in the system we needed.
After presentation and consultation with my management team I organised a project team tasked with implementing this new system.
I set up a system for internal and external feedback and communication, ensuring that everyone involved was on board and up to speed. I was very pleased with the outcome. I reduced the time taken to process customer refunds from 14 days to 2 days, saving over £100,000 annually in agent time.
3. Facebook Interviews’ Question Types and Examples
Facebook Interview Questions comprises three main types: fit questions, technical questions, and brain-teaser questions. Fit questions may appear in technical interviews, but are mostly asked during fit interviews. Technical questions are strictly limited to technical interviews, and brain-teaser questions may appear in all types of interviews.
No.1: Fit Questions
1. What is it
Fit questions are a type of question aimed at assessing candidates’ suitability for the role they applied for. They are role-dependent, and will be a combination of topics ranging from agile methodology or workflow, teamwork and collaboration, and conflict resolution.
For example, if you’re applying as a product manager, you might be asked the following fit interview questions:
- What’s a product you love/hate? Why? How would you improve it?
- How would you solve homelessness in San Francisco?
- Why does Starbucks sometimes have coffee shops on both sides of the road?
- Facebook has invented a technology that makes air travel 4x cheaper and 4x faster. What do you do with it?
- If you could implement a new feature for Gmail, what would it be?
- What will be the impact of self-driving cars?
- What technology trends are you following at the moment?
- You’re part of the Facebook Search web spam team. How would you detect duplicate websites?
- If you were to build the next killer feature for Facebook, what would it be?
- How would you determine if a new Facebook Search feature launch was successful?
2. How to approach it:
Remember, the main purpose of behavioural questions is to test your fit for the position you’re applying to. Hence, the key is to prepare 3-4 stories gearing towards the specific job requirements (professional experience, attributes, character, etc).
For example, if you’re applying as a software engineer, prepare 3-4 stories about your technical experiences, and don’t forget to include traits that make great software engineers (supreme communication skills, quick learning ability, good team player, etc), in addition to the aforementioned Facebook traits.

No.2: Technical Questions
1. What it is:
Technical questions are exclusively reserved for candidates applying for technical roles, such as Software Engineer, Electrical Engineer, Test Engineer, Network Engineer, to name a few. Coding interview questions often fall into the following categories:
- Arrays / Strings (38% of questions, most frequent)
- Graphs / Trees (29%)
- Dynamic Programming (18%)
- Search / Sort (9%)
- Linked lists (4%)
- Stacks / Queues (2%, least frequent)
2. Sample questions and solutions:
