As someone who was recruited to Intel relatively recently (and then, ironically, ISP'd because my inept manager when she gave me an S/SL4 for being "new to Intel"!), part of the pitch from Intel is that you're encouraged to make it a career and to learn and progress in the company.
It was, of course, all lies and the voluntary and involuntary turnover of the best people under my manager and within my group has been astronomical. She's since been promoted and I get regular calls from ex-colleagues wondering if there are openings at my new employer.
Intel is basically a counter-example of everything that one could hope of an employer (other than the decent salary and free fruit): slow-moving and bureaucratic, highly political, internally focused, lots of insecurity and uncertainty, ugly offices and lack of privacy and quiet to get work done, lack of candor and trust, limited paths for promotion and growth, really bad management and probably worst - few people ready, willing or able to actually compete and win at anything other than internal "Hunger Games" for resources, promotions and influence.
It's really quite different than what was described when I was on the outside being recruited away from a good job. Playing the Intel game offers few skills that are transferable to other, better employers, I guess, other than having "Intel" on your resume. My best advice is for prospective employees to stay away.
