Vantaggi
Data storage isn't going anywhere, this companys products are used in absolutely everything. Western Digital is one of the oldest Silicon Valley tech companies. Depending on the te, the culture is very great and the pay is fair. Very much dependent on the te though.
Svantaggi
Nothing is consistent in the company. It starves itself of basic investments to hit quarterly profitability numbers. The result of this is over-worked, under-resourced team members. It also means 50+ years of bandaids on basic tools and systems which causes some major inefficiencies and pointless problems. You'll find a lot of those issues at any public company though. At least that's what everyone at Western Digital tells themselves to cope with all the headaches.
