Pros
None that I can think of at the time that I left. There used to be many but it's useless to mention them now.
Cons
Marketing specialists and tech writers beware. The WD Marketing Communications department was a great place to work for quite a while. Alas, nothing lasts forever. The culture put in place by the present CEO, the first in WD history with no engineering background whatsoever, favored the hire of unqualified, self-aggrandizing, mendacious, and narcissistic top level managers. These individuals, who failed upwards spectacularly due to their advanced finger-pointing and responsibility-shucking skills, have some extremely broad definitions of job titles and their associated responsibilities. Unless you have a amazing talent for obsequiousness, can thrive in a hostile environment with high turnover, and can tolerate disrespect and laughingly unreasonable expectations, think long and hard about considering a job in the WD Marcomm department. If you have little to no experience and need to pay your dues and use this place as a stepping stone, I suppose it may work for you.
