Saferize Frontend Developer interview questions

Applied through AngelList. Phone conversation with each of the founders, Renato and Gustavo. Followed by a coding challenge. Then an in person interview. They said I went above and beyond on the coding challenge and I had a lot to offer the company even besides my development skills. The job posting that I responded to on AngelList said 90k - 150k salary + 0.2 - 2% equity, yet their first offer was for 80k + 0.5%. Reasoning: even though we were really impressed with your skills, originally we were looking for someone with more years of experience and because we had to pay the Full Stack guy more, we just dont have the budget and also because we have to make the most of what the investors have given us. I reminded them the range on the original job posting and pointed out the average salary for a front end developer in Oakland is 127k, and when I asked for clarification on questions like 1. when did you know your budget changed?, and 2. how come when we talked about compensation in the interview you were not upfront about the change in budget?, also 3. why has the job posting not been updated?, they said "it sounds like there are some communication problems" and revoked the offer. I do not do business with people like this and wouldn't recommend you do either.
