Absolutely! Contracts have many benefits to both parties, but stability is not one of them. A contract at Google sounds like resume gold to me. Many people commonly list the company they contracted for and leave off the agency and maybe say "Google May-Sept (contract)". I don't know Google's hiring practices but I do know that at many companies, going contract-to-hire let's you skip the full interview process. I have seen it personally many times from working in the industry. Contractors are usually hired after a single short interview.
