What people at Intel say
Reviews originally posted on Glassdoor.
Good job security, ability to move freely within departments to new roles, nice sabbatical perk every 7 years.
Broad scope and very good exposure to various domains. Good work-life balance.
Big organization and many opportunities. Not strong push
Hardware company is hardware focused. If you're in a product development, it doesn't matter much how the software is done as long as it's to hardware schedule.
WLB is great, flexibility at work, switching teams is good. Benefits are decent.
