I applied online. I interviewed at Automattic in Oct 2020
Interview
The process was impersonal, just questions via slack, had not much to do with JavaScript, if you don't have testing experience or TDD you probably be rejected a total waste of time, my "iterview" lasted 1 hour
Some questions were related to refactoring code and design patterns, so prepare for those kind of questions.
Some questions are related to performance and mesurement.
Interview questions [1]
Question 1
Tell us about a bug that you found and how you fixed it?
