Pre-interview Technical Challenge

khalilhughes-pilot-interview branch

Platform Choice

• Python (Flask) on Backend

• Node (React, Redux, Router) on Frontend

• css (Bootstrap) on Frontend

• I chose Flask because I haven't used it much and wanted to see if I could get it to run a single page application.

• I love using React, and knew that I would be handling all of the requests to Zomato in the backend. Using React I could focus on just building a Frontend client.

• For UX I chose Bootstrap, Mainly used it to create a simple container to so that the application was bit more presentable.

Installation

• Should already have Python 3 and Node installed.

• cd code-challenge

• pip3 install -r requirements.txt

• python3 script.py

if you are using a virutalenv

• virtualenv -p python3.5 code-challenge
• cd code-challenge
• pip install -r requirements.txt
• python script.py

Technical questions

Please include answers to the following questions in your APP_README.md markdown file.

1. How long did you spend on this technical challenge? What would you add to your solution if you had more time?

• About 17 hrs spread over 3 days.

2. What was the most useful feature that was added to the latest version of your chosen language? Please include a snippet of code that shows how you've used it.

• In the math library for Python, Tau has been which is about 6.28.

import math

findCircumference(radius): return math.tau * radius

3. How would you track down a performance issue in production? Have you ever had to do this?

• In this application I would start by checking the response times for client users each time a request is sent to backend.

• I have not had to this yet, but I have built other forms of analytics before.

4. How would you improve the Zomato API that you just used?

• I'd create a postman collection for the API so developers would be able to test it more easily.
• Next I'd write better documentation. And have pre filled inputs for users to try.
• Also the API is missing POST routes to add reviews and restaurants, that implies that I can't build a fully functional client into their API.

5. Please describe yourself using JSON.
