I was offered an On-Campus interview after submitting my resume through the career center and applying online via BPs website. I was interviewed by two people, one engineering and one marketing, and it took 1.5 hours. It was composed of behavioral questions and a short case study. Most questions were basic interview questions about my past revolving around leadership and teamwork. They asked separately for a SAR model situation(specific task, action, result). I was offered 2nd round to chicago.
