EXAMPLE OF BRIEFS
Let's dive into an example for a test, these are just some examples found on the internet and are not to be taken for one to one examples.
For example they don't even mention the deadline in which it needs to be completed or don't have any specific on how to tackle the texturing part. However, while the timeline is missing, the texturing and choice of asset part for example can be a part of the test, allowing a part of it to be open to interpretation and for you to figure out and show some initiative.
Often times briefs might even skip out on some details (maybe on purpose, but most of the time as a minor oversight) so you will have to assume certain small sections. These then become a test onto itself, and being able to fill in certain gaps and forming your own plan will be something that is expected more of you the more experience you have.
