This is an interview exercise for the Digital Products team of xtream. In the following sections, you will find a number of challenges that we ask you to implement. You DO NOT NECESSARILY need to complete 100% of them: you can choose to complete as many as you want.
⌚ We give you 1 week to submit a solution, so that you can do it at your own pace. We are aware that you might have other commitments, so we are not expecting you to work on this full-time. You will be evaluated based on the quality of your work, not on the time you spent on it.
Simply fork this repository and work on it as if you were working on a real-world project assigned to you. A week from now, we will assess your work.
Your work will be assessed according to several criteria. As an example, these include:
- Code quality
- Design Patterns
- Project Structure
- Work quality (commits, branches, workflow, tests, ...)
- Provided Documentation
We’re all about embracing the latest in AI, including GPT and similar technologies. They’re great tools that can provide a helping hand, whether it’s for generating ideas, debugging, or refining solutions. However, for this coding challenge, we’re really keen to see your personal touch. We're interested in your thought process, decision-making, and the solutions you come up with.
Remember, while using AI tools can be incredibly helpful, the essence of this task is to showcase your skills and creativity. Plus, be prepared to dive into the details of your code during the technical interview. Understanding the ' why' and 'how' behind your decisions is crucial, as it reflects your ability to critically engage with the technology you're using.
So, feel free to lean on AI for support, but ensure your work remains distinctly yours. We're looking for a blend of technical savvy and individual flair. Dive in, get creative, and let’s see what you can create. Excited to see your work. Happy coding! 🚀💼👩💻
We do understand that some topics might be unfamiliar for you. Therefore, pick any number of challenges and try to complete them.
❗Important: you might feel like the tasks are somehow too broad, or the requirements are not fully elicited. This is done on purpose: we want to give you the freedom to make your own choices and to put as fewer constraints as possible on your work. We appreciate if you could record any decisions, assumptions and doubts, together with any questions that you will ask in a real-world scenario.
Your task is to build the web application for FreshCart Market, a simple grocery e-commerce website, where you can search for products, add to cart, pay for the products and organize the delivery. The client does not want SEO or other similar features, so it is ok to have a single page application.
For the sake of this assignment, let's focus on creating the customer part instead of the admin part (which handles all the products and their available quantities)
Do not consider authentication, sign in or multiple users: for simplicity, imagine the user that is interacting with the system is always the same.
A junior developer started the project and created the list of the products available in the store. The products are paginated server side but the junior wasn't able to implement the pagination on the frontend. Comment and refactor the code so that it is more maintainable and reusable while implementing the pagination with infinite scroll.
There is also a search bar and a list of categories. The user can search for products and filter them by category. The search will happen when the user types in the search bar and the results will be updated.
On each product there is a button to add it to the cart. The cart is a simple list of products with their quantity and is handled on the backend. The user can add or remove products from the cart. And the number of products in the cart is updated in the header and also in the product list. The list is a bit slow to update and the junior developer wasn't able to fix it. If you end up succeeding on solving this issue, it would be great to provide some proof of the performance improvements. The add to cart functionality has also a bad user experience because of the slow backend, it would be great if we can do something on it on frontend Side to make it smother.
The last part to implement is the checkout phase, where the user can pay for the products and organize the delivery. The checkout is a multistep form with these steps:
- recap of the cart and final price
- the address where the products should be delivered and the delivery slot selection
- the payment method
- the confirmation of the order
