I had to interview devs when I worked in a tech lead position. So my take might be different than an hr person or manager involved in the same process. You really need to distinguish who the interviewer is before asking what they want.
The hiring manager usually has a different focus than I would even though we both are involved in the process. I would focus more on technical skills and he would be more concerned with the business skills, communication, and other "soft" skills.
In a general sense though the common theme of questions regarding the resume for all parties involved in the hiring process is to determine the accuracy and truth in the resume. I was surprised at the number of developers, native and foreign that lied on their resumes. I know it sounds naive, but I somehow assumed that our profession was above misrepresentations on resumes. Now I believe it's commonplace due to the increased demands for job competition, in my opinion. In my defense, I was in that role years ago and have learned a lot more since then.
On the technical side I would venture to say matching up technologies and years of experience in the candidate with what the position requires, desire to learn new things picking them up quickly, and a passion for the work play a large part in the hiring process. Vertical experience in the industry is generally a plus, but again, all this varies with the position and the company.
I've been able to get into positions and grow into them by having the above qualities and the fact that the company was having a hard time filling the position for the exact listed job requirement. For example, I've got a lot of ajax experience, so if a company is using a different library than what I've used before it's not a show stopper if they believe I can make the transition with the new technology, like Dojo to jQuery or vice-versa.
The reason I'm giving so many generalities is because what is important in one position and one company may not be the same for another.
