When I applied for the job, I had an interactive interview session with the hiring managers and 3 or 4 senior leaders within the organization. Most of them have been familiar with my work since it was an internal hire. SO the interview was relatively casual and revolved around my post-mortem analysis and learnings from a massive program in which I was a critical project lead. The interviewers were singularly impressed on a successful architecture change I made seamlessly midstream in a product.. something that was unsuccesful the previous two times. My advice for interviewers is to have a single most important achievement and have the explanation ready for why it is unique. Rest of the interview will get structured around it.
