Just be prepared for your RSUs to basically remain stagnant for your entire tenure because the hardware business is a boat anchor for the stock price.
(Zoom was started with 40 Webex (Cisco) engineers. lol.)
Also Cisco salaries are really low for SV, like 30% less - totally non-FAANG. I've pointed that out to Cisco recruiters, and they almost cried on the phone begging me to go to the next interview step anyway.
