Salary.com Customer Success Manager interview questions

The job posting claims the pay is $70,000 to $90,000, but during the interview process, you are told that the base salary is in the low 50's and that you could make 70 to 90. First and foremost, that is a SALES job, not customer success. Companies who don't understand the customer/client success is NOT sales are too obtuse to consider. Second, why put inaccurate and misleading information in the job posting? Don't waste my time or yours.
