There was a quiz with questions about OOP and frontend that I took onsite at the company's location. The quiz was about 50 minutes long and it was on the company's laptops
Very easygoing, interviewers were understanding, friendly atmosphere, mainly it was a discussion related to the projects that I have done (in a team + individually), technologies I have learned, specifying in detail the implementation process
The technical test was not difficult, I was asked basic oop questions and code snippet questions. The frontend questions were a little bit tricky tho. Expect jquery and javascript exceptions.
