Skybox Imaging interview questions

I had a phone screening interview about the position. The next week I was told that I would be having an interview through Google hangouts with 4 employees. The interview took about 3 hours. There were some fairly standard behavioral questions, questions about past work, a fairly straightforward coding question, and some general satellite knowledge questions. Nothing too difficult if you're familiar with the subject. Everybody seemed to enjoy their work and was very friendly. I was told I would be notified within a week, but it took three weeks for them to tell me I would be receiving an offer. Ultimately, I decided to turn down the offer. The main reason for this was due to the contracting agency that they were using for this position. The agency gave me incorrect information, wouldn't help with relocation, and were generally not very helpful.
