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.

Pregunta 1
You have a web page that displays a list of items (e.g., user posts). Some items contain very large images, and some have very long text content.
How would you optimize the loading performance and user experience when displaying this list?
Provide a practical example using HTML, CSS, and JavaScript to implement lazy loading or incremental rendering (e.g., render part of the list first and load the rest as the user scrolls).
Took about a month from start to finish, which felt longer than I expected. After a couple of initial phone screenings, I faced a challenging technical round focused on system design. It was during this round that I was asked to describe overcoming a major career challenge. Interestingly, I had just reviewed a similar framework on PracHub, which helped me articulate my thoughts clearly. Overall, I appreciated the depth of the process and ended up accepting the offer.

Describe Overcoming a Major Challenge in Your Career
The entire process usually takes 3–8 weeks, depending on scheduling and the specific role. Coding interviews heavily emphasize common DSA topics such as arrays, strings, trees, graphs, BFS/DFS, heaps, hash maps, and dynamic programming. System design becomes increasingly important for E4+ positions.

Given an array of integers and a target value, return the indices of two numbers that add up to the target
Unexpectedly, the first question in the technical round felt familiar. It was about finding a subset of strings with unique character concatenation — same problem I had worked through on PracHub a few days earlier. The interview included a recruiter screen followed by a rigorous pair of technical interviews where I tackled data structures and algorithms alongside system design concepts. After successfully answering a few more challenging DSA questions, I received an offer. The entire experience was intense but ultimately rewarding, and I happily accepted the position.

Given an array of strings, pick a subset whose concatenation contains no duplicate characters, and return the maximum possible length of that concatenation.
