The interview did not take long. Was asked about previous work experiences. Was give a couple of UI coding tests, which was based on simple js validation using bootstrap and creating a responsive layout, second assessment was creating a parallax scrolling effect using a svg image, with the help of js.

A lot of Javascript concepts. Closures, this, (call, apply, bind), but you're not allowed to use them until you're quizzed on them which is weird. Yes, I use call, bind, apply to deal with context and scoping problems. I can't stand being asked textbook solutions because it's not on my mind anymore. It's not liked I haven't used arrow functions thousands of times.
