The hiring process at CITGO is designed to be thorough, ensuring that candidates are not only technically capable but also a strong cultural fit for a large-scale industrial organization. Depending on the specific team and seniority, the process typically progresses from initial screenings to more intensive, face-to-face or video-based evaluations.
