applied through my university's career services. I was notified I was selected for an on-campus interview approximately a week before the interview. The total interview lasted ~30 minutes. The interview is set up in 2 parts. The first part is with someone working in HR for KBR. This person will make sure you have all the required forms (background check acknowledgement, etc) and goes through your resume and asks you random questions such as what did you do at this job or something of that nature. They were very broad questions. The 2nd interview was with the manager you would be working under. The interview was extremely straight forward. In my interview, the manager went through what the company does and i was shown the work KBR has done on recently completed projects and other projects that were half way through completion to show what the process looks like. The manager then went through the technical skills I listed on my resume and had me explain them and how i used them in previous jobs, projects, and classes. Just make sure you don't list anything on your resume you're not fully competent in because you will be "quizzed" on it. It's better to list skills you're actually good at than a bunch of skills you can't explain.

SIMPLE very straight forward asks on what is on resume HR came and greeted and then a general round on what are the projects and my role in it asked questions about my background and experience and my future prospects

Got hired at Open house. Very well organized. Interviewed with a couple of folks from peers to senior management
