Interview
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.
General HR screening & personality fit call, online programming questions, in person coding and case study final round. Overall friendly recruiters and great interviewers, some easy, some harder data structure and system design questions in the final round.
