Worley interview questions

Got a call from a recruiter and said they want me to go in for an interview for Associate Estimator position. The interview was oddly easy with the supervisor and two staffs in that department. They didn't ask me any questions like "why would you like join the company?" "what make you to join our department?" etc. Instead, they just described what is the job about like what it posted on the career board site and a lot of talking that doesn't really seem like an interview.

company is good, 3 people interviewed me, and they are all nice people, questions were easy, it's more like they want to know who are you and are you a fit to the company. Right after the interview, I kinda know I have the job, since I asked some questions that will hint that way.
