7Vals interview questions

It consisted of multiple rounds. First is an assessment of around 11-13 questions. There were only 3 LeetCode coding questions, the rest were mcqs mostly relating to DB. Even if you randomly selected the Mcqs, as long as you can answer all three coding questions, you will move to 2nd round, which is an interview. The questions are held on thier own website, and are made by them, but copied from leetcode, so its possible to pass some cases, and fail hidden ones. I answered 2 completely, and one partially. The questions were leetcode problems: Two numbers form third number,return indexes. Make ip address. Longest Valid Parentheses
