Ugam Senior Analyst interview questions

The interview was scheduled at 9:00, I reached there at 8:30,but interview was started post 10:30 as they were waiting for other candidates to come so that their lead can give an introduction about Ugam to all the candidates together. First round was a written round. So there were 3 business case studies and 2 SQL questions. They asked to write SQL code on paper. About case studies most company just want to see your approach , but here they were expecting some big essay type thing from everyone.
