SimpliVity interview questions

I submitted a resume, and then HR called with a phone screen. I had 2 sets of onsite interviews, both were with 5+ people and lasted first thing in the morning until after lunch.

Interview Process was a four fold process. It began with a phone interview by the regional manager, than followed up with an in person interview with the regional manager, then a phone interview with a potential peer and final interview with the local sales pairing. Phone interview and in person interview were fine, regional manager wanted to interview over a lunch, discussed a variety of topics. At the end of the interview, the regional manager, (after asking zero technical questions) told me he was concerned about my technical capability. He asked for me to interview with a potential peer for a technical interview. The technical interview was anything but. An hour long, maybe 3 technical questions and I had to correct their solutions architect on some specifics regarding latency components in storage. Dropped communication after that, so I accepted another position. Weeks later regional manager emailed to inform they had chosen another candidate (assumed at that point) but wanted to offer me another position. Graciously declined but happy to keep in touch. Again silence. The interview process would have been fine had the lack of communication not kept occurring.
