For the OA I solved 3 questions fully and a few points on the fourth.
4 rounds:
Coding round: Design bank system with Create account, Transfer, and get top Activity. Also also how would you make the code Production Level (edge cases, easily maintained)
Behavioral: 3 questions about learning style, handling conflict, and handling high pressure situations
Case study: talk about testing and when to use it, and a script that was giving an error, need to fix problem based for the given businesses
System design:
Design payment system
Did well on all rounds I thought, but didn't pass. Apparently coding needs to be quicker, or didn't explain though process enough
Standards seem very very high these days, I answered everything to almost 100% completion with time to spare. Hope this helps
