If you haven't been job-searching long enough to see how frequently this company posts essentially the same job listing, with various degrees of sales pitches and various degrees of professionalism, you won't necessarily know what you're getting into until you are in the interview and seeing some red flags.
I had a nice pre-interview conversation by phone with a HR manager after I had submitted my resume by email. Then, I arrived at the interview a couple days later only to discover that this HR manager, who had said she would be there to lead my interview, was out of the office, and the executive assistant did not have record of my interview having even been scheduled. Another person was there waiting for his interview, and I was brought in to the office along with him for a joint interview, with no acknowledgement as to why made to this other individual and no apology to me for their error.
The manager who lead the interview told both the other applicant and me some supposed reasons why he had selected us to come in. I almost called him on it; the office had no record of my interview, he had not seen my resume, and I still can't get over how he thought his glowing comments of me seemed genuine.
I was offered a position at the end of the interview, but the other application was as well. The other applicant was extremely introverted, and I sat somewhat in disbelief.
This is a sales position that eventually will lead to a sales position with maybe some management of lower-level employees. I think "management" means hiring/interviewing, like what I was going through.
I guess you are supposed to want this position badly, and I just wasn't buying what he was selling. I almost felt guilt-tripped for having major concerns about the job and about how people make a living without being a cut-throat salesman.
