It was good. they went through couple of OOP design related question and design pattern. Although this was my first interview outside my country therefore i was a bit nervous at the beginning but the person took my interview was very friendly. i felt confident after talking couple of minutes with him. he kept it going for about 30 -45 min i guess. based on my experience i would say MUM interview is not hard if you are working as a developer or you have prior programming experience. the thing is they usually looking for experience people so that their student can get a job on CPT after completing on campus courses. so be confident and express your self clearly so they can understand easily. all the best.
