If you need help from another team you do not usually work with and they will not help, what would you do?

"I got into Apple through an internal referral and interviewed for two EPM roles, but I completed the full process only for Siri. The Siri process took about two months from late January to late March, started with just recruiter emails instead of a recruiter call, then a short hiring manager chat, then a six person loop of 30 minute interviews, and then two additional director conversations. The whole thing felt much more casual than other big tech interviews I have done, with a lot of behavioral and project walkthrough questions, a lot of time left for my questions, and almost no real technical grilling. The most unusual parts were how many senior people I met, including directors after the loop, and the fact that my hiring manager came back in the loop and asked me zero interview questions. I passed the interviews, but I am still negotiating because the level and compensation came in lower than I expected."
