First got contacted by the hiring manager by phone and scheduled an in-person informal interview to discuss the position and salary expectations. Then got scheduled for a full day of in-person interviews with 7 people, which ranged from software engineers to peers to second-level manager. All interviews went well and consisted of discussions on what the position entails as well as specific questions on performance optimization, data modeling, technical architecture design, and past projects. Also some white board questions to jot down code samples and data models. All interviews went well, except with the hiring manager himself who started with "how do you feel about working hard?" and made it very clear considerable overtime was expected. he also asked a couple of very vague questions on data modeling and performance to which I didn't give good answers to. I'm pretty sure he was convinced at that time he wouldn't hire me.
