Backend Assessment - Blog Posts
In this assessment, you will write a simple backend JSON API. If you notice something
is not working (like the API, or any of the links in this document), please contact
.
This assessment will be evaluated based on the following criteria:
● Correctness: Is your solution complete and does it pass different test cases?
● Code Organization, Readability, & Maintainability: Is your code easy to read and
well organized?
● Code Performance: Is your code efficient? Did you use appropriate data
structures?
● Best Practices: Did you utilize good programming practices (write unit tests,
avoid anti-patterns)? Did you show a good grasp of your language/framework of
choice?
● Completion speed: A fast completion time comparable to the completeness of
your solution. This is the least important criteria.
We use the following rubric to evaluate your submission. Please note that if your
submission does not attempt to complete all of the requirements, we will be unable to
provide feedback on it.
Resources
If you are not familiar with how to set up a basic API, we recommend the following
resources:

this to be sure it still works as expected.
