When a company asks 4 hours of your time to come in and interview and in return don't spend just 5 minutes in an email writing that you didn't get the job... Say a lot.

very easy and laid back. nice people who genuinely want to get to know you. There are no tricks or games at all. It is just them asking you questions to better understand your life story and how well you will fit in the company. They are very genuine and straight forward.
