Experience:

A senior undergraduate Chemical Engineering student received an invite for an onsite interview with ExxonMobil for an entry-level Process Engineering role at their Baytown complex.

The candidate expressed confidence in the behavioral part of the interview process but sought advice on technical questions, as they had not encountered them in interviews before.

Community advice indicated that ExxonMobil is "notorious for questions around distillation" in technical interviews. General tips for technical interviews included pausing to gather thoughts, structuring the communication, and delivering answers in a calm, organized, and confident tone. Interviewers assess not only knowledge but also the ability to organize and communicate thoughtfully. Common pitfalls are blurting out answers without explanation or rambling due to a lack of structure. If the answer is unknown, it's recommended to describe a rational approach to the problem with existing knowledge and outline next steps.

Behavioral questions are typically STAR method-based (Situation, Task, Action, Result), covering situations like disagreements with teammates or recovering from failure. Safety and dignity are highly valued by the company. Candidates are advised to research ExxonMobil's culture, values, and leadership principles, and to prepare questions that demonstrate genuine interest in the company and the industry.
