Prerecorded video interview, followed by an in person interview. Both highly unprofessional, performed by unqualified staff.
Interesting dynamic for what I suspect is a legal pyramid scheme. Commission only, though they build up the idea that they get their "leads" from AT&T, as their crowning achievement. Leadership does not take criticism well, and sales force appears to be very young, weak, and likely gullible. They appear to prey on young, hungry applicants, pushing a "hip", friendly, workplace narrative, via buzzwords, and a distinct lack of transparency up until you get to the interview, and they feel they have "hooked" you. The fact is that this is a startup with an antiquated, unsustainable, extremely low volume business model that relies on customer leads from a single, non-affiliated source. I doubt leadership has ever managed a high powered sales force, and the frankly laughably underequipped office speaks to that idea.
"Account manager" is not the term that should be used to describe the position. You are applying for a door to door sales associate position, complete with field work. The "team building" aspect is simply interviewing, a job which should be reserved for HR, which appears to be completely absent.
If you were required to pay fees to retain the position, it would be a classic, textbook pyramid scheme, however, you instead appear to "pay" with footwork and sales, making it legal. Even the progression, and conjectured pay were reminiscent. (leadership even claimed "I made about $65k when I was in the field" when I told her I would need a very lucrative offer to leave my current position, claiming to make a 6-figure income, even with an office location worth perhaps half that)
If that doesn't turn you away, and you plan to interview, I recommend you be firm, stand your ground, and don't let them sell you on lofty ideas. Ground yourself in reality, and understand that "friendly office culture" alone does not produce results.
