Submitted my round 2 application the day of the deadline and received an interview invite on 3/1. Interviewed with a local alumnae on Thursday. Interview lasted for approximately one hour, but it was in the morning before work so it could realistically last longer if your interviewer has more time. The interview was relatively informal and casual. I did not send her my resume prior to the interview, but did bring to to the interview, and she reviewed it on the spot. She asked traditional questions - why an MBA? Why UCLA? She was really interested in my story and assessing my fit with the school. I really enjoyed the interview and learning about her experiences. Hope this helps!
