Wined and dined us through the whole thing. Flew us in the night before and put us up in a nice hotel downtown to make sure we were well rested. Hospitality was excellent through the whole process - I was offered snacks and drinks, they let me stop to play the office piano (a baby grand), and we were nicely fed. Even took us to a local brewery for drinks afterwards. The next day we headed to the roof of the building where we were able to overlook all of SF, and we were taken on a trolley tour of the city. Several technical interviews on day 1 followed by an interview with one of the three founders for a personality/culture fit on day 2. Overall one of the best interview experiences I've ever had. Ultimately I accepted a different offer but still use the Meraki interview experience as the gold standard when contributing to the recruiting process at my current employer.
