Perguntas de entrevista de vagas de Senior Java Developer/Lead da empresa Striim

I got one HackerEarth 90 mins coding exercise. There were 3 problems to solve with your webcam on. You need to code on HackerEarth page only, as you can't do any copy paste from outside neither from any other internet page nor from your local IDE. Problem statements were not properly defined with no proper examples, so it will take some more time to understand the problem statement.
