The interview is about 4 hours, where you will be individually examined by 4 different managers of the company. The interview is very technical, but you also get the typical questions as well. For example in the screening phone interview, "where did you go to school?", " what was your GPA?", and more. For the second interview, know all you can about centrifugal pumps. More importantly, tell them why you are interested in working there, what other jobs you have applied to and ( If like me you have had previous jobs) tell them directly why you left your last company? Also, what do you like about engineering and what don't you like?
