Look at the top review. They are going to ask you how to design a smart meter for multiple apartment buildings, then they are going to ask you 2sum closest to 0, then they are going to give you code and ask you to talk them through it, then they are going to give you a behavioral interview. Another thing: The people who interview you are not going to be the people you actually work with Oh, if you pass codesignal. You need something in the range of the 700s or higher, which is more forgiving than most companies that use codesignal Mini-rant: If you are going to ask everyone the same questions, then base your decision on whether or not they got the correct answer, then the people you hire are going to be the ones who memorized leetcode/glassdoor answers, not the ones who actually solve problems
