Pros
None that I recall. You do get benefits after 3 months but you only get 3 paid vacation days a year.
Cons
Worked for Welocalize for over a year in Sunnyvale onsite at Apple Inc. The HR team there is pretty much useless. They never want you to know any of your rights and if you are working under contract with them they never tell you when or why your contract ends. They literally call you after you leave work and tell you your contract has ended and you may not come back. You cannot even come back inside and retrieve your items from your desk. This has happened to several project leads all across the company, great workers just get slapped in the face after. If you have any doubts about the facts stated in this review, ask whoever is interviewing you before or after you get hired and ask what the procedure typically is when your contract comes to an end.The recruiter will give you a very vague answer I kid you not. They may blame this on the client but I feel like you should not stand for that as a well known company that hires extremely talented people. There are several contracting companies in the Bay Area that keep their employees well informed and also give them a decent notice of when their contracts end. This was an ongoing thing, about every month a good amount of people would get hit.
