I worked at World Fuel Services full-time (More than 3 years)
Great Place - Management allows you to work independently to get your job done.
Sometimes worked some long hours as a salaried employee.
Advice to Management
Keep up the courteous atmosphere.
Interview was set by a HR recruiter. Very unprofessional company, they don't follow up or respond to emails after interview. Wasted like 4 hours for the interview but no feedback.
