Great. you will be asked leetcode/hackerrank problems for one round, system design for another and a hiring manager interview. The leetcode round focuses less on the complexity so medium difficulty and more on the problem solving

Wonderful people and very clear on the questions asked. Not intimidating. Kind and patient with nervous interviewers. I would say that the best way to ace this interview is to know about the systems that they use: AWS lambda, know about functional programming, understand Typescript. All of these should be relatively helpful. Mainly, if you are working on your projects and taking ownership and responsibilities, you should do well on the first interview.
