During the video interview, the algorithm question was a 'count pairs with given sum'. Naive way is using a nested loop, the O(n) way is to use a hash map. Other questions included how to design an architecture talking to many APIs, given a page how to make re-usable components, and soft skills such as what makes you motivated to work, etc.

Answered algorithm question naively first and got guidance on doing the O(n) way. As for the system design questions I described a microservices architecture. The other questions are based on your familiarity of UI component frameworks such as React and Vue.
