As an additional piece of anecdata, I was also thoroughly underwhelmed by my offer (software engineer) at Tesla; they either maliciously or incompetently tried to get me to take an offer at new grad rates, and when I laughed the first offer away (a 30% pay cut to move into the heart of silicon valley), the return offer was just strictly worse than all the other offers I got. Negotiation led to a promised increase to match, but then the actual letter was lower than the negotiated amount. Was thoroughly underwhelmed at the entire process.
