Wow, did Victor prepare for these questions beforehand? He is able to answer each one smoothly and hardly pauses to think for any question before answering. If this is truly not scripted, then I have to say - Victor did a incredible job

[@MenAmongTheRuins77]

like those were junior level questions tbh

[@dragonborn1996]

​@@MenAmongTheRuins77Its not about the difficulty of the questions. These are in fact, very basic questions. But the way he delivers his answers is masterful because he doesnt hesitate or pause in any of his answer. Almost like he memorized a script.

[@nextDevSchoolLab]

This is a GREAT question!!!!! When I am interviewing someone for the role of experienced Javascript developer or any other role, I focus on problem solving and performance. Also, in my opinion, every Javascript developer needs to understand how Javascript works under the roots because, if you have a good understanding of Javascript fundamentals such as how the event loop works and how to manage the scope, for example, it will make a total difference in your code. Focus on performance and problem solving I'd say, that is the key for you to succeed in any interview.
