Interview Questions

Imagine you have been tasked by the Account Manager to create a basic reporting application that will allow the account manager to view complaints via a online portal. The company already has an internal json rest api that stores all the complaints that the business has recieved and the number of corresponding sales in that period.

The internal json rest api can be hosted locally using the following commands:

$ npm install -g json-server

$ json-server --watch db/db.json

1. Develop a basic reporting portal using any frameworks you see fit for purpose.

2. Allow the ability for the user to toggle Quarter and Month consolidation.

For example:

Month	CPMU
01 January 2012	5.47388874
01 February 2012	57.65682657
01 March 2012	12.12591551
01 May 2012	67.77995238
01 June 2012	93.67857009

Should be displayed as:

Quarter	CPMU
1	7.186971458
2	82.6888992

3. Within the report there are missing months when data are not available, these days should be displayed as 0.
