How to best prepare for Meta Internship

Question

Hi everyone, I recently accepted an offer for a Summer 2025 Software Engineering Intern position at Meta. I have about ~5 months before I start and want to make sure that I’m as prepared as possible by then.

Specifically, I’d like to improve my technical abilities as much as possible in ways that align with Meta’s ecosystem and expectations, so I have the best chance of succeeding and obtaining a return offer.

With this in mind, I was hoping to get advice for the most optimal learning paths to do so. Specifically, I was curious if there are:

Any Languages, Frameworks, Libraries, etc. that are heavily used in Meta that I am likely to encounter as an intern
If there are any Meta-specific or open-source technologies that are commonly used
What type of personal projects would help prepare me for my role at Meta

Thanks!

I'd highly recommend going through this question from a Senior SWE asking the same thing (most of it should apply to you as an intern): What can I do during my break to prepare myself as an incoming Senior Software engineer at FAANG?

When will you find out which team you'll be on? I definitely would not learn a random technology or framework that Meta uses; the company uses literally 100s of technologies, and it's unlikely that they'll use the exact tools that you're using. For example, a lot of the infra teams will use C++, while product eng will use Hack, while mobile devs will use Java/Kotlin or Objective C/Swift.

Once you know your team/manager, you can send them a short email expressing your excitement and ask what they'd recommend you to review.

Meta is so big that it's not worth trying to go deep on anything specific unless you genuinely have an interest in learning it.
