API Interview Question V2 - Refayat Haque - "Senior Backend Engineer" candidate - Toronto, Ontario, Canada

Files:

• lambda_function.py
  • Backend logic carrying out quote processing based on requests made from client-side (requests to lambda function are in the form of event objects/dictionaries)
  • I.e., the lambda function is what calculates the quote based on the data coming in from the client-side forms
• src/Input.js
  • Frontend logic and data capture is done here, frontend logic doing things like ensuring that the user cannot fill out more than one Pricing form (e.g., cannot fill out both Standard Pricing and Staggered Pricing)
    • Other frontend logic example includes blocking out the flat fee discount if the percentage discount is specified, and vice versa, in the Standard Pricing form

Documentation:
