HyperVerge Software Development Engineer (Backend) interview questions

Firstly, there was a coding round where 6 questions were asked and I did all 6 of them (3 were easy, 2 were medium and 1 question was tough). Second round was assignment round, task was to develop a backend for bus ticket booking system. Third round was Technical Interview (Live coding round). I did well is this round, but I was unable to answer CSE subject related questions as I did b.tech from ECE. After this, I got rejection mail. But May be after this round there was an HR round remaining.
