People who think all O&G companies are the same are either willfully ignorant or tasked with making sure employees don't expect better. They either never worked anywhere but XOM and have no idea what they're talking about or they are part of XOM management or HR.
All O&G companies are not the same. Other companies are not ideal but they're certainly better than "I'll fire employees using PIPs to save on severance" XOM. Don't fall for their propaganda.
