BG Advisors interview questions

Applied for one position, it was a struggle to find out the salary. Once I did, it was far below what I said I was looking for which explains why it was such a challenge. They suggested I interview for a different position, but I got another vague response on salary and eventually after asking several times got a range that was really just way too low for the position, but was told I could negotiate it. I chose not to go forward given how much of a hassle getting basic info was. Seemed like a huge red flag.
