Curriculum Associates Principal Software Engineer interview questions

I was received by a receptionist upon arrival. I would say that the receptionist appeared a little col. I assumed this person is used to many candidates arriving and leaving and thus doesn't care much. Anyway I was given a folder with company and product information while I waited which was nice. During my onsite interview I had multiple folks interview me asking me questions. There was a lot of white board sessions. I tried my very best to remain positive and answer as well as I can. One of the interviewers was a director and I felt this person's interview style was condescending and also did not know how to bring the best out of the candidate. I would say the HR folks who walked me around during the interviews were kind and also brought me lunch.
