Incipio Photo Editor interview questions

Got an email, a call, and a long test (remote), passed, and went to the interview. THe first one was by a man and a woman. They were professional and to the point. I seemed to pass that first interview and was asked to go for a second interview. There were two women asking questions this time. They seemed pretty nice but I felt like I could see why some reviews from past employees mentioned the word "highschool" in a negative because the atmosphere of the interview was somewhat casual but something was off-putting about the way they were talking to each other (maybe too casual and unprofessional compared to the first pair).
