ExxonMobil hires overwhelmingly through campus recruiting, and almost every account describes the same shape: a screen (campus 1:1, phone, Skype or an online numerical/personality test), then an on-site or in-plant final day made up of several back-to-back interviews. Behavioural and competency questions dominate at every level, with a single shorter technical block bolted on that is calibrated to the discipline: chemical/process fundamentals and P&ID reading for engineers, industry/accounting/corporate-finance basics for finance, and a live trading simulation for commodities. Wage and craft hiring at Gulf Coast sites runs on a completely separate track: a scheduled pre-employment aptitude test, a long silent wait, then batched interviews with a heavy cut before the final round.
These 23 writeups cover chemical engineering, mechanical engineering, project engineering and other roles. 21 of them were posted under a forum handle, so we could not verify the authors’ identities.
1Group discussionPanelA campus group discussion used as the first filter before anyone reached the interview panel. The author gives no detail on the topic itself.Covered: Group discussion, Behavioral
2Panel interviewPanelA single 45-minute session with three panellists covering technical, behavioural and communication ground at once. Roughly the first quarter was technical (training, minor and major projects, a research paper, and mechanics-of-materials questions grounded in how real structures fail), followed by an order-of-magnitude estimation puzzle and a long behavioural block on difficult teammates, pitching ideas, and moving from a robotics background into oil and gas. Results were announced within the hour.Covered: Past projects, Strength of materials, Guesstimates, Behavioral, Conflict handling, Career motivation
Cost Engineering Intern, Bangalore Technology Centre
1Resume shortlistTake-homeA pure paper screen with no fixed cutoff. The author's read was that a reasonable CGPA plus genuine, well-documented technical projects and positions of responsibility got you through.Covered: Resume deep-dive, Past projects
2Group discussionPanelHeld remotely the morning after a company presentation, with third-year mechanical and chemical students mixed into groups of twelve. About half an hour of open discussion on a general social topic, then each participant had thirty seconds to give their own conclusion.Covered: Group discussion, Behavioral
3Technical and HR interviewPanelA five-person panel that spent the first fifteen-plus minutes purely on the resume, then asked the candidate to name her favourite chemical engineering subjects and pulled questions from every one she listed. The panel probed conceptual understanding rather than textbook definitions, and closed with standard behavioural questions on strengths and weaknesses.Covered: Resume deep-dive, Thermodynamics, Fluid mechanics, Heat transfer, Behavioral
1Career fair and applicationBehavioralMet recruiters on both days of the fall engineering career fair, then submitted the formal application through the university's Handshake portal.Covered: Resume deep-dive
2Phone screenPhone screenA phone conversation with a manufacturing engineer who was an alum of the same school. The author describes it as getting-to-know-you rather than a technical drill, with the offer call arriving weeks later.Covered: Behavioral, Past projects
1Campus interviewBehavioralAn hour-long one-on-one on campus with a company alum, entirely behavioural, reached through a non-target school's recruiting pipeline.Covered: Behavioral, STAR stories
2Houston final dayFinalFlown to the Houston campus with a dinner the night before hosted by a non-interviewing 'day host', then three consecutive hour-long interviews the following day. Two were behavioural and one was technical, covering the energy industry, accounting and corporate finance.Covered: Behavioral, Domain knowledge, Accounting, Corporate finance
1Senior management interviewHiring managerA first-round interview with two senior people from operations and trading, focused on behavioural questions and the candidate's resume.Covered: Behavioral, Resume deep-dive
2Trading simulationTechnicalA one-hour live trading exercise. Other contributors on the same site note it assumes a working grasp of how crude is traded and hedged and what drives supply and demand.Covered: Trading simulation, Domain knowledge
3SuperdayFinalA final superday round that this candidate did not attend for logistical reasons, ending the process without an offer.Covered: Behavioral
1Online application and testsOnline assessmentAn online application form followed by an online numerical test and a personality questionnaire.Covered: Numerical reasoning, Aptitude
2Video interviewPhone screenA Skype interview built around competency questions.Covered: Behavioral, STAR stories
3Site interviewFinalA face-to-face interview at the Fawley site, again mostly competency-based with one technical question mixed in. The author reports the end-to-end process took six to nine months.Covered: Behavioral, STAR stories, Domain knowledge
1Recruiting dinner and campus interviewBehavioralA pre-interview dinner with the recruiting team followed by an on-campus interview.Covered: Behavioral
2Site interviewFinalA follow-up interview at the company's own campus, which did not lead to an offer.Covered: Behavioral
1One-on-one interviewBehavioralA one-on-one interview built on standard motivation questions plus a pointed question on how safety shapes the candidate's own behaviour, alongside a skills test and background check.Covered: Behavioral, Safety procedures, Career motivation
1Phone interview with the hiring groupPhone screenA professor referral put the resume straight in front of a group lead, and the entire process was one roughly 45-minute phone call with that group. Entirely behavioural and, by the author's account, very standard: motivation for joining and a failure story. Drug test and background check followed.Covered: Behavioral, STAR stories
1Campus interviewBehavioralResume submitted via career services after an on-campus info session, then a behavioural interview on campus.Covered: Behavioral
2On-site interviewFinalAn on-site interview that did not convert. The author rated the overall difficulty as easy.Covered: Behavioral
2Campus interviewBehavioralA one-on-one behavioural interview held on campus.Covered: Behavioral, STAR stories
3Final panel dayFinalFour back-to-back interviews: a task-prioritisation exercise, a technical interview, a behavioural interview, and a closing conversation with the area manager. The author rated this loop difficult despite the whole process taking under a month.Covered: Task prioritization, Domain knowledge, Behavioral
1Agency screen and phone interviewPhone screenThe opportunity came through a staffing agency rather than a direct application, starting with a phone screen.Covered: Behavioral, Shift availability
2In-person and site interviewPanelAn in-person interview followed by an on-site round, with a group element and a background check. The offer landed within a month of the first interview.Covered: Behavioral, Safety procedures
1Campus interviewBehavioralAn on-campus interview after an info session and application, described as heavily fit-focused.Covered: Behavioral, STAR stories
2Dallas final dayFinalFlown to Dallas a week later for a final day of five interviews, only one of which was technical. The technical bar was described as confirming basic financial competency rather than deep modelling. The candidate ultimately declined the offer.Covered: Behavioral, Corporate finance, Domain knowledge
1Associate and group leader interviewsPanelA two-on-one interview with associates plus a separate one-on-one with a senior group leader.Covered: Behavioral, Resume deep-dive
2SuperdayFinalA superday-style final consisting of two interviews, a dedicated technical session, and a closing conversation with the controller. The author rated it easy and accepted the offer.Covered: Behavioral, Corporate finance, Domain knowledge
1Online numerical testOnline assessmentAn online numerical reasoning test gating the telephone stage, referenced by both posters in the thread.Covered: Numerical reasoning
2Telephone interviewPhone screenA telephone interview made up of general competency questions. The poster declined to reproduce the questions, said there were no surprises, and reported not passing.Covered: Behavioral, STAR stories
1Video screenPhone screenA short Skype interview run by an outsourced interviewer who had no knowledge of the specific role, so the questions stayed generic and competency-shaped. Multiple posters in the thread put it at ten to fifteen minutes.Covered: Behavioral, STAR stories
2Face-to-face interviewTechnicalAn in-person interview with two project managers that the poster describes as the real hurdle: mostly role-specific discussion, closing with roughly ten minutes of chemical engineering technical questions such as reading a sketched process and instrumentation diagram and reasoning about what could go wrong and how flow and pressure behave.Covered: Behavioral, P&ID reading, Domain knowledge
3Assessment centreFinalAn assessment centre exists as the stage after the technical interview. This poster was rejected before reaching it.Covered: Behavioral
1Pre-employment testOnline assessmentA scheduled, seat-limited pre-employment test session run for Baytown-area wage and craft roles. Other posters in the same thread who sat it describe verbal reasoning, maths and mechanical aptitude sections where the time limit, not the difficulty, is the problem, and note a two-year wait before you may re-test.Covered: Mechanical aptitude, Numerical reasoning, Aptitude
2First interviewPanelCandidates who cleared the test were called in batches. This author was one of roughly fifty interviewed for a machinist opening but was cut before the final interview. Thread-mates describe the same pattern at other Gulf Coast plants and note that profiles stay on file for around four years, with callbacks arriving months or years later.Covered: Behavioral, Safety procedures
1Panel interviewPanelA single panel of three interviewers split into a technical section, a behavioural section and a general section. The panel told the author this is normally the whole loop for the role, with a second interview added only if they feel they need one, and quoted a decision inside about two weeks. The author was still waiting with the portal stuck on 'in progress' when they posted.Covered: Domain knowledge, Behavioral, Past projects
1Batched interview weekPanelInterviews for a Baytown process technician intake were run as a mass week-long event: the author reports hundreds of candidates cycled through across the week for 48 seats in an October start class, with far more people present on the day than expected. They posted again roughly ten days later still waiting on offers, so the outcome is unknown.Covered: Behavioral, Safety procedures, Shift availability
Process Technician Apprenticeship, Baytown Complex
1Online testingOnline assessmentAn online test sat a few weeks after applying, which gated the interview invitation. A separate poster preparing for the same trainee-operator track was told the process is two phases: a mechanical comprehension test and then an on-site interview.Covered: Mechanical aptitude, Aptitude, Numerical reasoning
2Interview weekPanelInterviews were run as a single scheduled block across one week for the whole intake class, with candidates told offers would go out roughly three weeks after that week against a fixed cohort start date a couple of months later. The author's portal moved to 'Application Under Review' a week after interviewing and then stopped updating, with HR not responding to follow-up email.Covered: Behavioral, STAR stories, Safety procedures
Materials Synthesis and Characterization Technologist
1Online assessmentOnline assessmentAn assessment sent before any human interview. The author does not describe its content.Covered: Aptitude
2Panel interviewPanelA single panel round covering the lab and materials role. The author was unsure whether this was the final stage or whether a technical or manager round followed, and was still waiting on a response when they posted.Covered: Domain knowledge, Behavioral
1Rounds 1 to 2: Screening interviewsTechnicalA chemical engineering PhD candidate describes clearing two interview rounds before the site visit, without detailing their content.Covered: Past projects, Domain knowledge
2On-site interviewFinalA final on-site round closing a three-round loop. The author posted weeks later still without a decision, which matches the slow post-onsite turnaround other candidates report.Covered: Past projects, Behavioral
1Rounds 1 to 2: Two interviewsPanelTwo interviews held in the same period for a refinery process job. The author's account is mainly about the aftermath: nearly two months later there was no rejection email and no change to the application status, which several other posters in the same subreddit report as normal for this pipeline.Covered: Behavioral, Safety procedures
