Pros
Nice office with thoughtful touches, notwithstanding the plumbing issues others have mentioned. They have attracted some very good engineers and developed some valuable if unproven IP. Crucially, Nio was established at the right time and place to catch the global push towards electrification to the great credit of Nio's founders in China.
Cons
Role of the San Jose office is unclear. SJ has groups working on “full stack” car tech from infotainment to autonomy, but hard to see how any is staffed to credibly compete with industry leaders. While upper managers hold generally impressive credentials, few have prior auto industry experience. This would seem to be considered a plus in the “Silicon Valley vs the world” narrative the company is pushing through keynotes and Glassdoor review rebuttals, although central value propositions have yet to progress past PowerPoint. Still, they are eager to cultivate a disruptive image through self promotion. As both a large company and a startup, Nio has somehow inherited the worst qualities of both: groups that seem to prefer to operate anti-synergistically, favoritism, title inflation (in some cases very laughable), entrenched non-contributors, and acutely, a defective company reporting structure in which even decent engineers would struggle to develop a Juicero, let alone a whole car.
