Orion Innovation Trainee Associate Software Engineer interview questions

I applied through college (campus placement) and the process took a day. A HR came to our college and presented about the company and the projects they do. The presentation was good and then we are given answer sheets with question paper for first round of interview which is MCQ's. MCQ consist of quants, reasoning, logical, verbal. I got selected from the 1st round and in second round they asked 3 programs to write in paper (Easy!!!). And then they said us that they will issue result in a week. But after some weeks I got to know that iam not selected..even though I wrote 3 programs correct. Some of my class mates said that they selected a girl as she registered earlier for the interview.
