Took all the three rounds on the same day. Round 1 : basic node and DSA. Round 2 : DSA and projects Round 3 : Projects and cultural fit round

First round was screening call with recruiter. It was a 20 min video call where he asked about myself, my work my project etc... I had some question for the company as well so that too I clarified on the call. Second round was problem solving. The interviewer was from US hence interview took place at late night. He gave a react problem (on hacker rank) where skeleton was made and I was to implement the functionality. The problem needed knowledge of DS and optimisation in react, you must also know how to write a scalable code.
