As technology develops, so does the number of software engineers or developers. Many software engineers or developers strive to be the best coder. They try to prove themselves in so many ways and one of them is the coding challenge. Many software engineers or developers use coding challenges not only to test their coding skills and algorithms in solving the use case problem but also to improve their skills. The challenges provide a variety of problems across different difficulties and coding practices such as recursing, querying, manipulating, etc. When solving a problem, a developer needs to pay attention to the time consumed by the code to make sure it is a solid solution. By doing coding challenges, they also develop and practice their skills to get better.
Nowadays many job recruiters tend to use coding challenges to test developers when they apply for a job. To see whether the applicants are up for the challenges in their future job is one of many reasons for the recruiters to use coding challenges. So doing coding challenges can be very essential in enhancing your career as a software engineer or developer. Many competitions are also held for developers to compete with others to win rewards from the coding challenge platforms.
