Amazon Web Services Software Developer interview questions

They contacted me online, and before any call or contact with a recruiter they sent me an online test with 2 problems, one of them was reasonable and completed very quickly, the other had a bunch of performance tests that would only pass if you code your solution with mathematical solutions in mind. Not the best cut for the people they want in a team in my opinion.

Technical Interview via hacker rank asked for 3 DSA-related problems and simulated their actual workflow, I haven't reached the next step but the overall interview was excellent and smooth. I am not sure about the next steps
