A 30 minute phone screen with their recruiter led to an hour-long phone-screen with one of their Europe-based Senior Solutions Architects. This led to a series of 3, 1-hour long face-to-face interviews at their offices in London with the hiring manager, a senior solutions architect and their VP of Global Professional Services (via video call to New York). A subsequent 1 hour video call interview with another solutions architect was the final step.
