Pros
Intel is a huge company with a stable future, plenty of growth, and decent leadership towards that growth. The work environment is typically clean, social, and safe, as Intel focuses on security and social interaction for profits. Intel frequently offers small amenities, side benefits like gyms, cafe's, coffee areas, open patios, etc. to their workers to improve the workplace "feel", to build a complete package of benefits to offset their slightly lower than market price in straight salary. Intel is a very social-conscious workplace, where your status is malleable depending on your network skills, ability to work with others, and innovation.
Cons
Huge company, and every Fab, area, and department are different in culture from every other. If you get a good manager, your job is wonderful. If you have a bad one, there is almost zero recourse to change that, and your career will suffer quickly. AS a large corporation, interdepartment politics plays heavily, and often workers suffer from the bad ideas of one department impacting others, and too often, silly decisions are made with no regard to impact on others. One example: In order to save money, the training department fired personnel who used to prepare the classrooms with materials, schedule classes, etc.. THen, every other department had to start printing their own materials for every class, schedule classes without a central booking feature, and suddenly, classes were held without teachers, without students, rooms conflicted because two classes were scheduled together, and every teacher suddenly spent hours more per class in the photocopy room, making booklets for classes than ever before. This lead to frustration, lost time, and an abandonment of the program by the volunteer teachers, which lead to fewer classes, which lead to fewer trained workers, which forced the training organization to hire new people to straighten out the mess, and we are back at square one, except our experienced class managers are fired, new, inexperienced ones are taking their place, and the teaching pool is reduced from frustration. And, thousands of man-hours have been wasted on the effort.
