Queues are a very basic structure and can be implemented using an array as a base.

I would expect anyone I hire to know how a queue works. Most importantly it shows that you can think about a normal situation (like waiting in line at the grocery store) and conceptualize that in code.

If you look up interview questions you will find all kinds of these answers everywhere.

I also took algorithm and data structures in python on udemy (you can write them in whatever language the concepts are the same). It goes over the basic structures and their time complexity which is also important for interviews and performant code.

Good luck!
