The OA consisted of 2 multiple choice questions and 1 coding question, all of which I would consider leetcode easy and rather straightforward. However the technical interview questions were definitely more around the medium-hard level-- you have to complete 3 stages of a wildcard regex matching question to pass. I think they reuse the same question for almost every interview, so definitely study your regular expressions! I finished the first 2 parts of the question, but unfortunately ran out of time to completely implement the 3rd part, which is why I was ultimately rejected.

I was only asked one question which due to language difficulties I failed to answer quickly enough. The question was pretty easy and went like this: You have an array of strings and a function that receives a string and returns whether it's good or bad. We know that starting at some entry, all strings in the array turn from good to bad and want to find this entry at O(logn) time.
