What is hoisting ?
The backbone of the client is rendered with `haml` and a Vue instance is attached to it. The task was a bit obfuscated, and as it turned out later there were 2 parts to it: 1) The HTML was awfully syntactically wrong, and that was the first opportunity to make comments and improve the code. 2) There was some vanilla JavaScript in the Vue file that needed to be converted to Vue. I missed the second part in my preparation to the interview and that was the reason I failed. I got nervous --> froze during the interview and I wasn't given a second chance. 15 minutes after the interview ended I realized what I did wrong, corrected everything and made some suggestions, fixed the unit tests and the failing CI pipe, but there was no reply on my actions/email and I felt like I was cut off cold turkey with no feedback from the tech lead a t all. Now, that's a bit harsh.
