Reg Expedia Tech Screen

Hi friends, I have technical phone screen with expedia. What do i expect from expedia technical phone screen? Am a senior java developer and if i have to attend expedia technical phone screen will it be just coding round or will there be technical interview questions? will there be any coding questions using codepad or hirevue? is there any specifc areas which we should be prepared for technical questions and coding questions? thanks in advance for any help!
