Contracts
Most companies have their own contracts they send to you. Make sure you read every line and understand everything you are signing. When you talk to a recruiter, verify what the hourly rate they are offering is and make sure it is in addition to your housing, expenses, etc; not including. Every company quotes their prices differently and if you can get that in writing (such as an e-mail), it will help you if the contract doesn't reflect what you've already discussed.
