You don't need to write complex code to look smart.
The simpler a piece of code, the more clearly it will show that you put effort into it.
Simplicity is not easy. It isn't something you can do right away.
In my experience, it's far more difficult to write simpler code than complex code
Had the fortune or misfortune of working with senior devs who were masters in writing convoluted code. They gave the crazy excuse that it was for job security but it only ended up ruining their vacations😂
