I received a message via LinkedIn for an interview. Shortly after replying, a quick phone call was set up to determine my interests and how they align with the work available at Facebook.

After that, a phone interview was conducted to screen candidates. This interview involved actual coding done using a shared online notepad.

Then, an in-person interview was conducted, which consisted of four interviews:

• Algorithms
• System design
• Class design/algorithms
• Behavioral

There was also a break where I could ask an engineer any questions regarding the company.

Results came back within a week after the in-person interview.

I've signed an NDA, so I cannot discuss the details. However, you should prepare for:

• Sorting algorithms
• Pattern matching algorithms
• Design problems, such as how to implement certain features on Facebook
• A review of your previous work experience, to discuss some topics in depth during a behavioral interview.
