First interview by basic China HR so you can expect 30 mins of your time being wasted by useless questions. Pass. Second interview is technical. Nowhere near the level of what you would expect from Lead iOS interview. I'm being interviewed by a medium/junior iOS dev about detailed niche question related to tools Adidas has chosen. No question about architecture etc. His English ability also seems to be not so good. Pass. 3rd phase: homework. I build a small iOS app for them. I wait 2 months for feedback, but their useless HR is unable to communicate so I tell them I'm no longer interested.
