1) Coding question: leetcode easy (mimic a storage system).

2) System design: banking system to support 4 different types of transactions. Scalability and availability follow-up questions.

3) Case: this is similar to the Youtube video case study about the ING acquisition and customer approval logic. The business scenario is straightforward (CapitalOne is coming up with a new type of credit card) and what are the pros/cons of this service. Was asked to analyze a function with complicated if/else/if. My analysis indicated that some of the input arguments and code were redundant. Summarized the purpose of the function in 1 concise sentence, and rewrote code for correctness and clarity.

4) Behavioral. This was very enjoyable. Talked about a few situation from past experience (tell me about a time when you disagreed with your manager, tell me about a time when you need to learn something new, etc).
