Hate is a really strong word. And Intel isn't worth the energy that it takes to truly hate. I've moved on.
That said, my short experience as an employee at Intel was nearly uniformly negative.
From being recruited from a good job to a job at Intel on false premises (it ended up being very different than what was advertised), to being treated like a child despite having nearly 20 years of high-level experience in my domain, to being thrown into a really difficult position, doing everything I was asked to do and more, then questioned on whether I was "aligned with our strategic goals," to using my personal network to rapidly bring on an amazing team, to my own boss undermining me with my own team (they told me), to being stabbed in the back from HQ (I was remote), to seeing the handful of employees that I trusted and respected quit or be run off by incompetent politicians doing stupid things, not making necessary decisions and being disingenuous. Finally to be ISP'd after my first full year FOCAL for the sin of being "successful" (despite all of this).
There were just hundreds of ways that working at Intel was just a negative experience. Maybe some people thrive in that culture. I certainly did not and was planning to leave - like so many of my former colleagues - after the next annual bonus. I got a severance package instead.
I can hold my head high in that the work that I did (and tried to do, despite meddling, ignorant as*holes like my boss and her boss) was excellent. It received external awards and praise at the highest levels outside of Intel. And I acted as a professional throughout, despite really being treated poorly and being lied to nearly endlessly.
Do I hate Intel? Nope. Will I do everything in my power to buy other-than-Intel products for the rest of my life? You betcha...
