RoviSys Software Engineer interview questions

After interviewing with 10 people for 4 hours I was called back on a later day because the right people had not been around the first time I interviewed. Came back second day and talked with another 6 people taking another 3 hours. After all this I received an email stating that I was not a fit for the company. After inquiring why that was so that I may use the feedback to better myself I was told there was no real reason, I just wasn't a fit.
