There is a Codecignal OA which is the hardest part of the interview. I am pretty sure you don't need a perfect score. With the OA, there are also situational behavioral questions. After the OA, you will have a power day, which consists of behavioral, coding, and case interviews. The coding question is more about design and I think it is much easier than a leetcode-style question. The behavioral is standard and nothing surprising. The case interview I had was about the cloud, but you don't really need much experience with the cloud. There was a table that showed the price of different VMs, and you have to decide which is the most cost-effective. You are then given a piece of code, and you have to find issues with it and resolve the issues that are present in the code.
