Senior Engineer Test

Develop a service that simulates basic banking operations in a programming language of your choice. This service will manage accounts, process deposits, withdrawals, and transfers between accounts.

The system should be designed reflecting real-world constraints of a bank.

Requirements:

1. A class or set of functions that allow:
   • Account creation: Allow users to create an account with an initial deposit.
   • Deposit: Enable users to deposit money into their account.
   • Withdrawal: Allow users to withdraw money from their account, ensuring that overdrafts are not allowed.
   • Transfer: Enable transferring funds between accounts.
   • Account balance: Provide the ability to check the account balance.
2. Database:
   • In-memory data storage will suffice, no need to have a database alongside the project, but you can add one at your discretion

The word “service” here is used in a “software component/module” rather “deployable unit with an API” sense, no need to provide API for it.

Feel free to take as along as you need to complete the exercise. This will be used as a base for a follow-up pair programming session.
