 1 | # Senior React interview questions
 2 | 
 3 | ## What we will cover
 4 | 
 5 | * Interview questions that I would ask a mid to senior level React developer
 6 | 
 7 | ## Notes
 8 | 
 9 | Before we start it is important to note that interview questions for juniors and seniors have a different goal.
10 | 
11 | In the junior case we are interested in figuring out if there is a potential in the candidate to become productive and in the senior case we are looking for experience.

13 | The following questions are aimed to figure out how much experience a candidate has and if they know what it means to work on big projects.
