Must bring development environment. 2 45 minute coding sessions and 2 45 minute selling sessions. Difficult to code that quickly. The first problem wasn't too hard but to get a working version w\once all was understood was nearly impossible. Second problem had math I hadn't seen in 15+ years so difficult. The two talking sessions involved people selling the company to me instead of asking about my experience which would have been beneficial to me. Not interested in other than doing the problems which were more appropriate for a new graduate than a Senior Engineer.
