Comments about this company having a toxic culture seem justified based on my experience - offered a 2nd interview and then pulled it as my salary expectations were too high (then why offer in the first place) and based on a deck I’d not even had a chance to present.
Original interviewer didn’t even bother to follow up directly but got HR to send a boilerplate response.
Stay away! Clearly have no regard for people and an amateurish and unprofessional culture.
