what kind of challenges can be completed with a code challenge?

code challenges have become more popular in recent years as a way to quickly identify qualified candidates for software engineering jobs. Code challenges are a type of coding competition where applicants are asked to solve a complex coding problem in a given amount of time. This can range from solving simple coding problems to building entire applications.

One challenge that is often included in code challenges is algorithm solving. This involves writing code to solve complex algorithms, which tests both problem solving and coding ability. These types of problems can involve mathematical algorithms, data manipulation, or other types of calculations. Algorithm solving challenges require participants to think critically and come up with creative solutions.

Another kind of coding challenge involves building web or mobile applications from scratch within the given time limit. This requires the candidate to have knowledge of programming languages such as HTML5, CSS3, JavaScript, and React Native, as well as other web or mobile development frameworks like Ruby on Rails or Express.js. The applicant must be able to write efficient code that is optimized for performance across multiple devices and operating systems while still creating an appealing user experience.

Finally, most code challenges also include debugging rounds where candidates must find and fix errors within existing codebases. This tests applicants' debugging skills and understanding of object-oriented programming principles such as abstraction, inheritance, and polymorphism. These situations require the participant to locate errors quickly and employ best practices when making changes to the existing codebase.
