Key Interview Questions for Recruiting Full-Stack Developers

Finding the right full-stack developer can be a challenge, whether you’re in IT recruitment or project management. The success of your project hinges on bringing on board developers with not just the right skill set but also significant experience. Conducting thorough interviews is one way to ensure this. Below are refined questions and insights to guide you in interviewing candidates for full-stack developer positions at Globy.

Multithreading enhances CPU utilization by allowing multiple threads or executions to occur simultaneously, supported by the operating system. This capability enables a program to handle multiple user requests or perform various operations concurrently, optimizing process management through simultaneous execution supported by the OS.

This model divides applications into three distinct layers: the presentation layer, or front-end, which is the user interface; the application layer, or back-end, which processes data; and the database layer, which manages data storage. This structure is crucial for separating concerns and enhancing application scalability and maintenance.

While completely preventing data scraping from a public API is challenging, implementing rate limiting is an effective deterrent. Rate limiting restricts the number of requests a user can make within a certain timeframe, issuing an HTTP error 429 (‘Too Many Requests’) if this limit is exceeded. Other strategies include blocking requests based on user-agent strings and issuing temporary access tokens for session management.

In JavaScript, a callback function is passed into another function as an argument and executed at a certain point within that function. This allows for asynchronous or synchronous tasks to be performed within the outer function, leveraging JavaScript’s non-blocking capabilities, especially in Node.js environments.

Referential transparency is a concept in functional programming where an expression can be replaced with its value without changing the program’s behavior. This principle supports predictable and bug-free code, facilitating easier understanding and maintenance of the software.
