Screen candidates with the highest quality questions

We have a very high focus on the quality of questions that test for on-the-job skills. Every question is non-googleable and we have a very high bar for the level of subject matter experts we onboard to create these questions. We have crawlers to check if any of the questions are leaked online. If/ when a question gets leaked, we get an alert. We change the question for you & let you know.

How we design questions

These are just a small sample from our library of 15,000+ questions. The actual questions on this ExpressJS Test will be non-googleable.

🧐 Question
Medium I/O cycle and main module Event Loop	Solve
Review the following NodeJS code: Pick the correct statements: A: X will be logged after Y always B: Y will be logged after X always C: The order of executing timeout and immediate callbacks is non-deterministic and is bound by the performance of the process D: In this case, the function calls are scheduled in the main module and not in the I/O cycle E: In this case, the function calls are scheduled in the I/O cycle so setImmediate is always executed before any timers scheduled in the I/O phase, independently of how many timers are left
Easy Res methods	Solve
If none of the methods (res.download, res.end, res.json, res.jsonp, res.redirect, res.render, res.send, res.sendFile, res.sendStatus) are called from a route handler to terminate request response cycle, what happens to the the client request? A) Will be left hanging indefinitely B) Will get an internal server error - 500 C) Will get a service unavailable error - 503 D) Will be left hanging for a while and then request timeout error - 408
Medium Phases and Timers Event Loop	Solve
Review the following NodeJS code: Pick the correct statements: A: Adaface will be logged after Lovelace. B: Lovelace will be logged after Adaface. C: Once the asyncOpThatTakes195ms completes reading the file, it starts executing the callback which takes 10 seconds. Only after this is finished, the event loop will execute the timers that are finished. So the timeout call back will actually be executed after 205 ms even though it is scheduled to be run after 200 ms D: Once the asyncOpThatTakes195ms completes reading the file, it starts executing the callback. While executing the callback, the scheduled timer becomes ready to be executed. So the runtime executes the timer and then completes processing the callback.
Medium Async Await Promises Promises Async-Await	Solve
What will the following code output? A: 24 after 5 seconds and after another 5 seconds, another 24 B: 24 followed by another 24 immediately C: 24 immediately and another 24 after 5 seconds D: After 5 seconds, 24 and 24 E: Undefined F: NaN G: None of these
Medium Bitcoin prices Axios Promises	Solve
Review the following JavaScript code and pick the correct options: Assume that the API returns a successful 200 response code and a JSON object as the response body. What would the value of ‘a’ be after the code is executed?
Medium My Module Scope	Solve

Test candidates on core ExpressJS Hiring Test topics

Routing in Express: Routing in Express refers to how the application handles different HTTP requests and directs them to the appropriate route. It essentially maps the requested URL to the corresponding handler function or middleware, making it a crucial skill for building dynamic web applications.

Setting up Express application: Setting up an Express application involves installing the necessary dependencies, configuring the application settings, and creating the basic file structure. This skill is important because it lays the foundation for developing and running an Express application.

Serving Static Files in Express: Serving static files in Express allows the application to serve HTML, CSS, JavaScript, and other static files to the client. It ensures that the web pages are properly rendered and the necessary assets are loaded, making it an essential skill for web development.

Creating and Using Middlewares in Express: Middlewares in Express are functions that have access to the request and response objects. They can be used to add functionality, perform validation, handle errors, and more. Being able to create and use middlewares is important for building robust and scalable applications.

Using Template Engines: Template engines in Express allow for the dynamic generation of HTML pages by combining templates with data. They simplify the process of rendering HTML on the server and enable code reuse. Understanding and using template engines is crucial for developing dynamic web applications.

Debugging Express: Debugging Express involves identifying and fixing issues or errors in the application code. It requires understanding the error messages, using debugging tools, and troubleshooting the code to ensure smooth operation. Being proficient in debugging Express applications is necessary to deliver high-quality software.

Node.js Fundamentals: Node.js fundamentals encompass the core concepts and features of Node.js, including event-driven architecture, non-blocking I/O, modules, and file system operations. Knowledge of Node.js fundamentals is important as Express.js is built on top of Node.js and understanding how it works under the hood helps in building efficient applications.

Javascript Coding: Javascript coding refers to the ability to write clean, efficient, and maintainable code using the Javascript programming language. Strong Javascript coding skills are essential for developing server-side applications using Express.js and effectively utilizing the various features and functionalities it offers.
