Who is it for? 

There are coding challenges for jobs and for the ambitious programmers seeking to better and exercise their skills. Even during the hiring process for technical work, employers use challenges for interviews so these websites are great for coding interview practice.

Competitive programming enthusiasts also make use of these challenges to work with teams or gain speed in coming up with solutions. In general, online coding practice can benefit anyone in the industry, from the novice to the pro, because the challenges are tailored to your level, and especially for beginners, this can be a great way to advance faster.
