Never got an interview with anyone, I simply received pre-formatted emails that invited me to take a test (the usual cognitive assessment and an English test) which I passed followed by a CodeSignal SQL assessment and told me they'd get back to me the following week.
Never heard back from them, as far as I can tell the test never got graded either. I reached out and got ignored (of course, there was no human interaction or real communication in the entire process). Not even the decency of letting me know they were no longer considering me, zilch.
If you you receive such invitations I highly suggest you think twice or thrice about it.
Utterly unprofessional and from what I can tell it's just Uber's modus operandi to ghost candidates.
