Here are a few good starter interview questions for potential candidates in an interview:
- What is your experience with Node.js and Express.js, and how have you used them in previous projects?
- Can you explain the concept of RESTful APIs and how you have implemented them in the past?
- What is your experience with NoSQL databases, such as MongoDB, and how have you used them in your projects?
- Have you worked with React, Angular, or Vue.js? If so, which one and how have you used it in your projects?
- How do you ensure the security and scalability of your applications?
Another good interview strategy is to provide a set of requirements and have the candidate walk you through how they would build out the application.
Here is a set of requirements for an example application and an outline of how a candidate might build it:
- The application should be a simple to-do list manager that allows users to create, edit, and delete tasks.
- The application should have a clean, user-friendly interface.
- The data should be stored in a database and accessed using an API.
Building the Application:
Plan the application architecture: The candidate would need to determine how the different parts of the application will work together and what the overall architecture will look like. They may need to create diagrams or flowcharts to help them visualize the process.
Design the database: The candidate would need to determine the schema for the database and create the tables and fields that will be needed to store the data. They may also need to design any relationships or indices that will be necessary to support the functionality of the application.
Create the API: The candidate would need to build the API that will allow the front-end to access the data stored in the database. They would need to decide on the endpoint structure and the methods that will be available (e.g. GET, POST, PUT, DELETE).
Integrate the front-end and back-end: The candidate would need to integrate the front-end and back-end, making sure that the data can be seamlessly retrieved and saved to the database. They would also need to test the application to make sure that everything is working correctly.
Deploy the application: Finally, the candidate would need to deploy the application, making it available to users. They would need to decide on a hosting platform and ensure that the application is properly configured and optimized for production use.
This outline provides a general idea of the steps a candidate might take to build the example application. The specific approach and tools used may vary depending on the candidate’s experience and the requirements of the project.
