Uber Software Engineer interview questions

Usual process for uber: 1 online (Algo & coding) if pass: Onsite: 2 Algo + Coding 1 Hiring manager 1 bar raiser 1 system design All online because of the pandemics. All interviewers were great and friendly.

Was forwarded between 3 different recruiters before even having the initial call. Went on to a frontend interview, where the interviewers were react developers, I am a react developer, yet they forced me to use vanilla JS, like you would have in 2010. Wasn't prepared by the recruiter for this, expected leetcode type challenge or react. Why you would test a candidate in something they never claimed to have experience in, and the company doesn't even use, on top of that without preparing them beforehand. All in all the worst of all the recruiting experiences I had so far and a total waste of time.
