Facebook is an online social media and social networking service owned by the American company Meta Platforms. It employs around 72000 people across the globe and is ranked 27th in the fortune 500 rankings.

 

Many people aspire to be an employee at Meta because of the company’s unique culture which promotes both personal and cultural growth. The recruitment at Meta is broadly a 4 step process:

  • Resume Screenings: Recruiters will screen your resume for technical requirements, education, and experience, to check if you’re a potential fit. 
  • Phone screenings: There are usually two rounds of phone screenings at meta:
    • Pre-Screen(20 mins): HR recruiter will contact you to ask a few behavioral questions on the phone to assess your background and qualities.
    • Technical Phone Screening: A Facebook engineer will ask some questions from your resume for 10-15 minutes, then you will be given one or two coding questions (e.g. data structures, algorithms, etc.) on a simple online code editor, to be solved within 30 minutes,
  • On-site Interviews: This involves 4-5 interviews with a team of recruiters, each interview lasts for about 45 mins. For Technical roles, there are two main types of interviews. 2 or more interviews for each type.  
    • Coding on-site interviews: whiteboarding solutions to slightly harder data structures and/or algorithmic problems.
    • System Design on-site interviews: You will be asked to come up with high-level design architectures for real-life products. 
  • Hiring Committee reviews: It is more like a candidate assessment meeting where team leaders/ managers will determine whether you’re a good fit for their respective teams.

Facebook SDE Roadmap

 

Why this sheet?

Landing a job at Facebook is challenging. Facebook as a recruiter has high standards which is justified as it is one of the most iconic tech companies and also the competition is tough. We have come up with this sheet to help you beat that competition and grab your dream job. This sheet covers all the important and popular technical questions asked in Facebook interviews so far. Questions in this sheet are grouped topic-wise and cover all major DSA topics that have weightage in meta interviews.

Resume Builder

The sole purpose of a resume is to make you land your dream job. It introduces your qualifications, skills, achievements, and everything regarding your expertise. It helps you land your career. When you have a perfect resume, nothing can be a hindrance to the best job.

We have our own resume Builder which can help you build a powerful resume to get through the resume screening round. You can check it out here- GFG resume builder

Phone screenings

  • Behavioral Skills

    Many people are very afraid of behavioral interview questions in technical interviews as they seem to be just something most programmers are not good at.

    Unlike technical questions, which are very standard and usually have clear answers, behavioral interview questions are much more flexible and sometimes may make candidates quite uncomfortable. We have tips for Prepare Behavioural Interview Questions

  • Technical Phone Screening

    Even though telephonic interviews have many benefits, including the flexibility to attend from anywhere and the ability to go back to notes, there are still some complexity and problems that are part of them, so you must be ready for them if you want to be approved for final selection.

    We have prepared tips to crack a telephonic Interview.

Coding on-site interview

Array: An array is a collection of items stored at contiguous memory locations. The idea is to store multiple items of the same type together.

String: Strings are defined as an array of characters. The difference between a character array and a string is the string is terminated with a special character ‘\0’.

LinkedList: Linked List is the data structure that can overcome all the limitations of an array. A Linked list is a linear data structure, in which the elements are not stored at contiguous memory locations, it allocates memory dynamically.

Tree: A tree is non-linear and a hierarchical data structure consisting of a collection of nodes such that each node of the tree stores a value, a list of references to nodes (the “children”).

Graph: A Graph is a non-linear data structure consisting of nodes and edges. The nodes are sometimes also referred to as vertices and the edges are lines or arcs that connect any two nodes in the graph.

Sorting and Searching:

  • Sorting: The sorting Algorithm is used to rearrange a given array or list of elements according to a comparison operator on the elements.
  • Searching: Searching Algorithms are designed to check for an element or retrieve an element from any data structure where it is stored.

Stack and Queue:

  • Stack: A stack is a linear data structure in which elements can be inserted and deleted only from one side of the list, called the top. A stack follows the LIFO (Last In First Out) principle.
  • Queue: A queue is a linear data structure in which elements can be inserted only from one side of the list called the rear, and the elements can be deleted only from the other side called the front. The queue data structure follows the FIFO (First In First Out) principle.

Dynamic Programming: Dynamic Programming is mainly an optimization over plain recursion. Wherever we see a recursive solution that has repeated calls for the same inputs, we can optimize it using Dynamic Programming.

System Design

System Design is the process of designing the architecture, components, and interfaces for a system so that it meets the end-user requirements. System Design for tech interviews is something that can’t be ignored!

Almost every IT giant whether it be Facebook, Amazon, Google, or any other asks various questions based on System Design concepts such as scalability, load-balancing, caching, etc. in the interview. This specifically designed System Design Tutorial & System Design Course will help you to learn and master System Design concepts in the most efficient way from basics to advanced level.
