# 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.
