Bounty-Finance-Decision

You are given a task to build a handy tool for a large bank which will aid them to make quick decisions on giving out loans to potential borrowers. This tool will analyse the financial status of the borrower based on few inputs and gives a score to make a decision. You see the potential that this can be sold to other banks, so you need to think about how to build this application in a customisable way

The task

There are 2 different personas who have 2 different interfaces. Each interface has 2 parts. The 1st part is the bare minimum requirement, the 2nd part is a bonus round

Persona	Interface	Description
Product Head in the Bank	The admin configuration page	He defines what fields to be captured and what decision making rules to be run
Sales Agent	The financial summary page	He collects the financial data (based on above configuration) and sees the decision

---

Persona 1 - The admin configuration page

Part 1

The user should be able to specify what fields need to be captured. Example below

Field Name	Field Tag	Field Type	Formula	Mandatory
Name	name	Text	NA	Yes
Age	age	Number	NA	Yes
Type of Income (Salary, Business)	income-type	Radio	NA	Yes
Income	income	Number	NA	Yes
Expense	expense	Number	NA	No
Balance	balance	calculated-field	income-expense	No

Part 2

The user should be able to specify the rules for scoring based on above fields. Example below

Rule tag	Formula	Score
age	age <= 20	0
age	age > 20 && age <= 30	10
age	age > 30 && age <= 50	5
balance	balance <= 20,000	0
balance	balance > 20,000 && balance <= 75,000	5
balance	balance > 75,000	10

• Total Score = age score + balance score
• Final Decision = If total score > 10 then give the loan, else reject

Persona 2 - The financial summary page

Part 1

Based on the admin configuration this screen will automatically generate the necessary fields and the user (sales-agent) can capture these details

According to the above example, the user will see a form which asks for Name, Age, Type of Income, Income, Expense and Balance. If the admin adds a new field called marital status then this page should show that as well

Part 2

Based on scoring logic defined by the admin, we should be able to see the total score. As per the above example if age = 25 and balance = 50,000 then loan eligibility score = 15 and the loan can be give

Things we are expecting

1. components - dynamic fields - text, dropdowns, validations all defined at an admin level
2. problem-solving - parse a text-y formula and calculate the scores
3. Ease of usability
4. Test cases

Final Words

When you are done, please just create a pull request on this repo. We would like you to come in and present your code to the whole team.

May the force be with you!
