Ah ok. Article is paywalled for me so I couldn't see that.

8% of what? All employees, or engineering? (435/0.08) ~= 5400, and Uber's S-1 filing says they had 22,263 employees as of 31-12-2018.

(ed. - article says 27,000... but Uber's had three low-hundreds firings chunks tallying ~1260 total over last summer, and said they were freezing engineering hires. Were the extra 8k hired in the first half of 2019?)

There were a few rounds, totaling at least 1000
