I had 2 phone interviews. The first one was behaviorial and the second was a little technical+behavioral. But both interviews were conducted in such a way that I felt comfortable throughout. Then I had a assessment center invitation, which consisted of : 1. Presentation 2. Role play simulation 3. Technical Interview. Presentation was on a topic they gave beforehand. Role play consisted of an individual selling the product(decided beforehand) and Technical Interview was based on documentation provided beforehand. I felt the assessment was conducted in a very comfortable setting, i never felt out of place. I also got an opportunity to interact with assesors and interview conductors during lunch, i think that interaction helped my case a lot. Personally, my role play was horrible. my presentation was ok. It was a 10 minute presentation and 5 minute QA, but when i presentated, I finished my presentation in 5 minutes and they gave me a 10 minute QA. I should give a warning, all questions asked on presentation were very difficult, and thought provoking questions. Which in nature of itself was very interesting to me, and I answered in a discussion type of way. My technical interview was perfect. They told me that it would 2 weeks before they get back to me. To all who are preparing for this interview, prepare hard for role play. That holds of weight.
