During a screening call the recruiter mentioned a minimum of 2 days/week office attendance is required. I make significant impact working from home where I can focus well. That's harder in an office. Also my foot injury makes commute tough. They seemed insistent on working in the office despite temporary disability. I got rejected soon after without feedback. Maybe they were looking for someone with more experience, yet the hiring manager never spoke to me despite the fact that I've worked on similar technical projects before.

It is actually a series of interviews, starting with introductions of both yourself and the company, over to discussing some part of your previous work and then to a few technical interviews. All are designed to get to know you and determine how good a fit you are. In previous work interview, a specific thing was selected and I was given the opportunity to really dive deep and explain all the things I did or did not do or was prevented from doing. The more information the better. Good and bad stuff. The point was to see how deep I can go and how I deal with various aspects of work, technical / political / personal. Technical interviews are not that hard. Architecture one was interesting. Was given a problem to work on that seemed simple in the beginning but with change of requirements (again, the idea is to see how I deal with change) it soon became quite nice scaling problem. Had a good time there!
