Marathon Petroleum's loop, as far as public first-hand accounts go, is a short and heavily behavioral one that starts on campus: a career-fair or recruiter conversation, then one or two interviews with the hiring manager and one or two colleagues from the function. Interns and co-ops report being asked to walk through technical coursework or project work in depth, to show leadership and clear communication, and to demonstrate that they researched MPC itself (refining basics, company values, recent corporate news). Hourly refinery and terminal operator hiring runs on a different track that MPC documents in its own job postings: a pre-employment assessment battery, a work-demonstration test, a physical abilities test, plus medical, drug/alcohol and background screening.

1Campus career-fair conversationHiring managerFirst contact was an in-person conversation with a manager from the finance department at the candidate's university career fair. The recruiting reply came back the following Monday, so the whole process ran under a month.Covered: Resume deep-dive
2Virtual behavioral interviewPanelA roughly half-hour video call with two finance managers. It was entirely behavioral, centred on how the candidate adapts to different working environments and on examples of taking the lead. No technical or modelling exercise.Covered: Behavioral, Leadership, Adaptability
1Internship interviewBehavioralA former MPC engineering intern, answering another student's question about what to expect, described an interview where you have to be able to discuss technical material in depth even if it has nothing to do with oil and gas, and where the interviewers also probe for leadership experience and evidence of clear communication.Covered: Past projects, Domain knowledge, Leadership, Communication
1Co-op interviewBehavioralA former pipeline integrity co-op described the interview as one where knowing Marathon itself is what separates candidates: its operations, its values, its current news, and the shape of the role you applied for. Having your own researched questions ready for the interviewer was treated as part of the evaluation.Covered: Company research, Domain knowledge, Behavioral
1Co-op interviewBehavioralA former refining chemical engineering co-op said the interview mixed behavioural questions with a check that you understand what Marathon actually does and roughly how refining works, including being able to talk about live corporate news (the Andeavor acquisition was the example given, which dates this account to the 2018-2019 recruiting cycle).Covered: Refining process basics, Company research, Behavioral, STAR stories
