Toptal Frontend Developer interview questions

The process was very quick and straightforward and the people were very kind. First the HR interview about me and my background. Then as a frontend developer you can choose to do a frontend challenge, which gives you 3 questions and 2 perfect scores are good to go. Then a technical interview with two questions one being frontend challenge and other is an algorithm. I failed at the algorithm, but I am planning to take again after some months. You do not need to take the tests you passed already.
