In an interview with Vulture published earlier this week, Rockstar's Dan Houser made mention of specific members of Red Dead Redemption 2's dev team working 100-hour weeks. He later clarified the statement, and a number of current Rockstar employees have since spoken of their experience within the company. 

As reported by gamesindustry.biz, Rockstar San Diego tools programmer Vivianne Langdon spoke first by declaring the most she's ever worked in three and half years at the company is "maybe 50 hours a week". Moreover, she describes this as a "rare occurrence", before detailing the intricacies of her experience with paid overtime.
