Speaking only for the positions my team/department: Our positions include a small challenge. You need to add a small feature or improvement via a Pull Request on Github to some code and ping pong with your future team members.
The goal not only to see technical skills but also how do you work together with the current team members, how do you handle critics in your code, how do you structure your changes, etc.
The challenge is not difficult, but we value the time and courage of the people who took part in it. My team tends to focus its energy in those.
If the job description gives you a chance to highlight yourself from the rest, take it!.
