I don't think it's a rejection yet. They can still accept you later on. However, if you didn't receive acceptance two weeks after the interview that means that they are still considering you as a possible future student, but they are not ready to make that decision yet. I was in the same situation last year. My interview was in November and I was under review for five month and then they placed me on the wait list. Unfortunately, I didn't get off the wait list at that time. Be patient and may be you will get in. Their stats for accepted students last year were 20/20/20 for DAT and GPA 3.5 SGPA 3.4, so if your stats are in the same range than you still have a good shot.
