I applied through a recruiter. I interviewed at Meta (Seattle, WA)
Interview
I only did the first technical screening with a developer and this involved 2 technical problems, in my opinion they were easy type problems. One involved merging two arrays and the last one a tree type questions. Nothing hard really, but at the time I was a bit confused on how to optimized things. Regardless, the interviewer was very nice and gave good hints in order for me to complete both problems in time.

Question 1
Design Twitter and consider if it was suddenly an extremely low latency env
Grateful doesn't even begin to describe how I feel about landing this role. The interview loop was smooth and friendly. They kicked things off with a technical round where I faced a DSA question about verifying an alien dictionary. Lucky for me, the time I'd spent on PracHub paid off, as it had the same type of problem just days before. After that, I had a system design discussion and a behavioral interview. Everything felt very collaborative, and by the end, I received an offer that I was thrilled to accept.
Interview questions [1]
Question 1
Given a list of words written in an alien language and the order of letters in that language's alphabet, determine whether the words are sorted lexicographically (Verifying an Alien Dictionary). Walk through the comparison approach using a character-to-index map, the O(C) time complexity where C is total characters, and how you'd extend it to handle words with mixed-case letters or words containing characters outside the given alphabet.
