Coding problem1
This was a machine coding round and I was allowed to use the internet to look for syntax (if need). The problem was a mix of LLD + Coding. The focus was more on OOPS, LLD, and are you able to provide working code for the same.
Algorithms/Efficiency was more of low priority to be checked in the same.
1. System Design Question
I was asked to design the Splitwise app APIs in my favorite language using the editor of my choice. Design Splitwise like API's with following functionalities -
1. Create User
2. Create Group
3. Add user to group.
4. Add Bill to a Group.
5. Get balance/settlement of a group.
6. Get balance/settlement of a user.
7. Allow configurable option to simplify the debts of users in a group.
Additional: 1 user can be part of multiple groups, 1 group can have multiple users and multiple bills.
Problem approach
Step 1 : Defined the entities
Step 2 : Define their relationships, identify 1-to-1 and 1-to-many relationships.
Step 3 : Define the database and how it will perform the operations.
Step 4 : Define the classes, methods, and their relationships using the suitable framework (in my case I used python with Django).
Step 5 : Write the code for individual methods to finish the code.
Step 6 : Write unit-test cases using a suitable testing framework.

Coding problem1
It was more focused on HLD and do I know the internals of the components I am using in design. The design has to cover all the scenarios from solving the problem to maintainability, reliability, and scalability.
1. System Design Questions
Design a logging pipeline solution for the application instances in the following scenario -
1. Apps running on VM's
2. Apps running on Kubernetes, but log collection agent running as daemon sets.
3. Apps running on Kubernetes, but log collection agents running as sidecar containers.
Problem approach
Tip 1 : Think about each component and why is it required in the flow.
Tip 2 : Think about various ways logs can be generated/emitted.
Tip 3 : Ensure each component is scalable and provides either Active-Active or Active-Passive HA.
