Another reason: "You're primarily interested with salary." Sounds like this company prides itself on overworking their employees and paying them less than what they're worth. (Which is what a lot of companies do , but they aren't proud of it.)
Employers pay their employees exactly what they're worth - by definition. If an employee is dissatisfied with their pay, they have the option to either negotiate a higher salary or find another job with higher pay.
