Imminent interview questions

There were 3 rounds of interviews for a job title that I still don't know what it was to this day, I put Marketing Coordinator as a placeholder. Each interview was run by a different person who claimed they were the hiring manager so I'm not sure who actually makes the decision. They all mentioned the process that everyone goes through from starting a manager training program and then working your way up to a Marketing Manager. I mentioned how I didn't want a sales job, all 3 of the hiring managers told me it wasn't and then proceeded to talk about how sales is a big part of your role. They told me normal work days are 8 hours but they flex so if you have to work til 7, you don't have to start until 11am, which other reviews say otherwise. I asked about starting salary and they said you start at a base of $550 per week and then work your way up to $1,000 per week after a few months before becoming a Marketing Manager that starts at $75,000, so the pay jump is pretty significant if you make it through the program apparently. You scheduled a next interview during the one you're in, so it definitely felt more that they are just trying to get people in the door and start working rather than finding good fits, which tells me the turnover rate is astronomical. I'm not sure who could possibly live off the starting salary unless you just got out of college and you're looking to get your foot in the door while living with your parents. They seem like nice people and all, but it felt like they weren't telling me the whole story about who they were and what the company was about throughout the process. My advice is find something else unless you absolutely need a paycheck, because between the good reviews from only current employees and bad reviews from only former employees, not much adds up about them. There's a reason there are so many bad reviews.
