I’m a bit confused; I thought many-to-many relationships typically needed just two tables, but now I’m second-guessing myself.

I feel like it might actually require three tables because we need a junction table to link employees and skills.

I remember practicing a similar question, and I think it was two tables for a many-to-many relationship, but I could be wrong.

I think this is a many-to-many relationship since employees can have multiple skills and vice versa. But I'm not sure about the number of tables needed.

Okay, the key is that employees can have multiple skills and a single skill can relate to multiple employees. That sounds like a many-to-many relationship to me.
