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.
1 leetcode med, 1 leetcode hard. make sure you know your DSA and leetcode questions. I wasn't able to get an offer bc i didnt complete the second question. Got a reply 2 days later saying they would move on
