Coding test is a programming challenge that assesses a developer's coding skills and problem-solving abilities. Coding tests can be used in a variety of situations, such as during the hiring process, as part of a professional certification program, or to assess a developer's current skill level.
Here are some details about coding tests:
Types of coding tests
Coding tests can range from simple challenges that can be completed in minutes to more complex projects that can take hours or days.
What to expect
During a coding test, you may be given a problem to solve and asked to write code to solve it. You may also be asked questions about your thought process while you're coding.
How to prepare
To prepare for a coding test, you can practice coding on a whiteboard or blank sheet of paper. You can also get used to writing code without an integrated development environment (IDE) or compiler.
How to take the test
You may be given a link to a code editor and be able to choose your programming language. You should make sure to take the test in a quiet environment where you won't be distracted.
How recruiters use coding tests
Coding tests can help recruiters assess a large number of candidates effectively because they can use an auto-grading system.
