One of the
greatest obstacles for many businesses is finding and recruiting a skilled
software developer.
As a result,
many businesses use coding challenges as a part of the interview process to
ascertain if developers have the qualifications for the position.
Testing a
software developer's skills and talents with coding challenges is a terrific
idea. These tests can be used as exercises to assist software engineers become
better programmers or as part of the hiring process.
You must be
ready to take on coding challenges, which are a common component of interview
procedures if you're an ambitious software engineer searching for work in the
sector.
This post
will go over 16 coding challenge interview strategies that can help you
succeed. However, let's first have a better understanding of the coding
difficulty before continuing.
A
coding challenge: What is it?
A
programming task known as a "coding challenge" is used to evaluate
the skills of software developers. It is essential to examine candidates'
coding abilities because they are required for software developers.
The
preliminary stage of a technical interview is basically this. There are many
programming challenges you may participate in even if you're not searching for
work to hone your abilities.
Below, we
have explored the best coding challenge websites.

most well-known websites for learning to code is HackerRank. Know the following
before using HackerRank:

contests provided by HackerRank are a better way to mimic a "real-life
interview."
Students and
learners looking to learn a new language should use HackerRank.
Engineers
are able to apply for available employment at businesses using their HackerRank
score, which can be easily viewed online.
If the
business you're applying for is listed in the LeetCode Premium area, consider
subscribing and practicing there.
Choose the
HackerRank coding tasks if the organization you're applying to is smaller than
FAANG (Facebook, Apple, Amazon, Netflix, and Alphabet's Google). In either
case, pay attention to one platform at a time.
