Completed 3 years at Cisco this month as a Hardware Engineer, joined straight out of a tier-2 college in 2021.
Over my 3 years, what I've learnt is that Cisco is just riding on the monopoly it has in the networking space. There's basically no innovation when it comes to Router hardware, and we basically reuse existing designs, packaging them as "newer and better" products. No risk, no Ishq 🙁
There's absolutely zero investment in R&D, and any new feature that gets added to the products only comes in after one of the competitors launches them, keeping Cisco behind in the game.
If Cisco keeps going like this, I'm sure the likes of Arista and Juniper will over us in the next couple of years, even with the new "Silicon One" that Cisco's promoting.
PS: I can only speak from a Hardware PoV, and I'm not quite updated with what's going on with Cisco's SW offerings.
