The overall interview rounds consists of 4 rounds, out of which 1 one is short hr call where he/she will be asking basic hr questions and few questions related to the tech stack you are applying for.
2 round was assignment which you have to complete within 4 hours and share the github link for the same.
3 round is a technical round based on the assignment you submitted and few questions related to programming and node js, the questions were easy but because of some misunderstanding from my side I was not able to give the right solution so it's better to clear all your doubts before going for the solution.
4th and final round was supposed was supposed to be a call with the ceo of solvative but since I was not able to clear the 3 round I got the rejection via email.
