Cavallo interview questions

There was a phone interview at first and a technical interview in person at their office in Grand Rapids which was taken by two software engineers. The technical interview was an hour long.

I was interviewed by 2 Software Engineers. They asked me a technical question that i was able to solve optimally, including many different tests. They decided to move forward with another candidate. Not sure why they wasted my time as I spoke to an engineer before this interview and they seemed to have slots open.
