Meta E4 Interview Experience
Summary
Interviewed at Meta for E4 role. Passed coding rounds and system design, but outcome not specified.
Full Experience
Applied for an E4 position at Meta. The interview process had three rounds. The first round was coding, where I faced two questions: finding the longest palindromic substring and implementing array flattening. The second round was a system design question about creating an Instagram news feed, which required considering read/write patterns and data storage. The third round was behavioral, focusing on past accomplishments and learning experiences. The interviewer emphasized aligning answers with Meta's values like leadership and teamwork.
Interview Questions (1)
Find the longest palindromic substring (easy). For a substring, if it is a palindrome and its length is greater than 2, then after removing the first and, the interviewer nodded in agreement throughout.
