Meta, formerly Facebook, is hiring big, even as its ongoing scandals show signs of hurting its employee-retention rates.
The firm wants to snag 10,000 job candidates to build out its vision for the metaverse, and beyond that, the social-media giant is aggressively adding to its 58,000-strong employee base to build out apps and services such as WhatsApp, Instagram, and Oculus. 
A document obtained by Insider gives insight into how the social network performs the technical interview, the first major hurdle that candidates have to clear along the way to getting hired — showing how seriously Meta and Facebook take screening talent. You can read the full document below. Meta declined to comment for this story.
Several developers told Insider that Facebook, and Meta at large, had a reputation for having one of the most rigorous interview processes in the industry, as well as some of the highest pay offers. The entire Meta interview process would typically span four to eight weeks, with about seven interviews, the tech-salary database Levels.fyi indicated.
The technical interview comes after the candidate does a screening call with a recruiter to discuss their résumé, experience, preferred coding languages, side projects, and overall professional history. If that goes well, the candidate advances to the technical interview.
The six-page document, which is shared with candidates for senior developer roles, advised the candidate to study the guide thoroughly leading up to their interview. It said that even « the most experienced engineers need to prepare and practice » so they can avoid appearing underqualified while solving problems under time constraints.
While the corporate entity itself is now known as Meta, the document referred only to Facebook, which is now technically a subsidiary of the new parent organization. The document is shared with candidates before their initial interview, but it’s otherwise not widely available.
The guide showed that the initial technical screening is 60 minutes and covers topics such as technical leadership, cross-functional collaboration, and coding skills. 
The interview itself begins with behavioral questions, which the guide suggested might sound like « Tell me about a successful initiative you worked on that required collaboration across teams. » And while the senior software-engineer role at Facebook doesn’t involve people management, the firm still asks the candidate to prepare to discuss any leadership experience, which might include road-map planning, resolving cross-functional conflict, and setting technical direction.
The next part focuses on technical acumen, with the candidate given 35 minutes to solve two coding problems. It suggests that Facebook has moved beyond the fiendishly difficult trick job-interview questions for which companies such as Google used to be famous, but that candidates should still expect a challenge.
« Don’t be surprised if the questions sound contrived, » the guide said. « Problems may be different than what you’re probably tackling in a day-to-day job. We won’t ask a ‘puzzle’ question, but questions may be different than real-world questions because they need to be described and solved in 10-20 minutes. »
The guide said the interviewer would ask the candidate to show their work, rather than have them just dive into the code. The firm expects candidates to be able to discuss why and how they chose their approach to solving each problem, including explaining the logic behind the code itself.
To prepare for the coding interview, the guide recommended that the candidate « block out time every day » to practice. The document showed that Facebook uses the CoderPad.io platform to present candidates with their coding challenges in remote interviews, and it uses a physical whiteboard for in-person interviews. The guide suggested that candidates practice with both ahead of the technical interview.
Assuming the candidate passes this stage, Levels.fyi indicated that candidates would go on to more rounds of interviews, which may vary from team to team. Those additional interviews may focus on cultural fit, design philosophy, or even more coding challenges.
