We had a OA on hackerearth and now I'm shortlisted for a interview which is in a week. Does anyone know what the company is about. I couldn't even find their website. And what do they ask in interviews. The role for which they're hiring is Software Engineer. But the JD has generic requirments like operating systems, DBMS, Networks.
