Johnson Controls Design Manager interview questions

Recruiter call, hiring manager interview, panel interview with 3 peers, 2 on 1 and 1 on 1. No portfolio review or case study reviews. Total time spent interviewing was ~4 hours. Hiring manager and peers were open, smart, humble, and engaged. The process was incredibly lengthy with minimal communication around timelines and expectations. I first applied on February 01 and as of April 17, have just now declined the role offered because the process has taken too long. Also, there were several times when the recruiter said they would get back to me by a certain deadline and they didn't make that deadline (e.g. recruiter told me on Apr 5 that they would get back to me with answers on Apr 7 and as of Apr 17, I haven't heard from the recruiter nor the hiring manager). There seem also to be miscommunication between EU and US teams around role expectations (e.g. I was handed off to a US recruiter after initially talking to an EU recruiter who told me the role could be US based remote, then, only when I was being offered a role was I handed back to the EU recruiter who then told me the role was EU remote). If a role is being offered with relocation assistance, it wasn't clear to me why the global mobility team wasn't offered as part of the initial offering. Instead, I was offered a sign-on bonus, to be paid upon arrival in-country, that came nowhere close to the rate of international relocation costs. When I said I'd need relocation assistance in the form of global mobility, the recruiter first said that shouldn't be a problem and then stopped communicating with me. By the end, it felt like the company and team didn't feel like I was a valued candidate or that I was being given a serious offer. My only conclusion at this point is that I was ghosted so the company didn't have to renege on their offer and open itself up to liability. Salary offer for EU was competitive.
