Meta Software Developer interview questions

I went through a web developer interview at Meta, starting with an initial online round to test my programming and problem-solving skills. After passing that, I moved on to deeper technical rounds, where they focused on my Front-end knowledge like HTML, CSS, and JavaScript, and asked me to optimize page performance and handle large images and long text efficiently. They also evaluated my Back-end skills, including connecting the front-end to the back-end, designing APIs, and managing databases. I faced practical challenges that required writing live code to solve performance issues or handle large data lists, and sometimes system design questions to create a platform capable of supporting millions of users. Finally, there was a cultural round to assess my fit with the company’s values and team spirit. Overall, the interview felt like a real test of my ability to think quickly, write clean code, and solve real-world problems effectively.
