JS and Angular interview questions (Work in progress)

In the last weeks, I have been working on doing some technical interviews for a new frontend in the team I am on. So, I’ve been recompiling the list of questions I have asked and I’ve been thinking about how to structure the questions.

I like to start the interview doing some questions about their working experience, what things he/she feels proud of in their previous projects.

And then, I start doing some JS verifications and after that, the Angular questions. So, here it is some of the questions that I made.
