Microsoft Programme Manager interview questions

There was a career fair I went to where I met recruiters and a program manager and software engineer. i spoke with them about my interest in cognitive science. It helps to pitch yourself and your ideas rather than let them talk to you. They liked my ideas and who I was I think and sent me an invitation to interview and attend a pre-interview session. I spoke a great deal asking the right types of qs at the pre-interview session and because I outshined everyone else I assured myself entry into the next round. However at the on campus interview they realized I suck at coding, I have taken very basic courses, and it was not enough to be a program manager. The person I interviewed with said he loved my communication skills and what I was about but I would get killed in the next round of coding questions. They never emailed me back to tell me yes or no I just assumed no.

Interviewer called me. This was the first interview (phone). The interview consisted of two questions: 1 problem solving, and 1 design question. Problem Solving question: You are given 9 marbles. 8 weigh the same. 1 is heavier than the rest. You are given a scale. The max number of weighs you can do using the scale is 2. How do you determine which marble is the heavier one without weighing more than twice. Design Question: How would you design a watch for University students? The rest of the interview consisted of usual behavioural questions.
