Flowserve R&D Engineer interview questions

Applied on company's website in early September, a phone screening with a recruiter in late September, a phone interview with hiring manager in mid October. The interview with hiring manager includes describing my past research during graduate school and behavior questions. No tricky questions. Onsite interview with two directors (supposed to be three but one traveling) at Temecula in early November. Mostly behavioral questions. Weeks after, received a phone call from recruiter that the offer will be likely made. Received the official offer in early December. Did not negotiate. The initial offer was good enough.
