Currently feeling unfulfilled and stuck at intel -- wondering what companies are the best for growing your career within HW disciplines?
Intel is a disaster for anyone working in hardware. They take promising talent and then ruin them by making them work on the same things over and over again. After 5 to 10 years of this, your career will be ruined because you will not have developed any new skills and you'll be similar to a new hire while demanding senior pay. I know this because I've interviewed many people from Intel. Leave asap for a better company with higher pay and more interesting work.
I have friend that were on Intel (in your same situation), leetcoded for some months and went to google. They do not regret it at all, they really dislike Intel.
