First I completely a moderately difficult email architecture project that was to be turned in. That was approved and I was then moved to a phone screen and finally an in person interview. The in person interview crossed many departments, first with HR, then was brought to lunch by a few engineers. After wards I met with the VP of Engineering and a few more engineers. HR asked clarifying questions about Klaviyo, how career development works and why I would want to work there. The Lunch interview was definitely an engineering culture interview which went nicely. The interview with the VP of Engineering was reasonably tough asking about my current company's API architecture which I did my best to explain but admittedly could not describe to a finite technical degree. Finally the last interview was a collaborative coding exercise where I was to refactor a snippet of Python code to be more efficient and easier to read whilst explaining my thinking to the other engineers. Throughout the interview I could tell there was a deep focus on general DevOps knowledge of deploy processes and large scale data processing as a focus.
