More interview help?

So I have another second interview this week. This time it’s for a job outside of social services. The position is a Calendar Clerk at a law office. The job would be keeping schedules for the lawyers, when they have to be in court, when paperwork is due, which people should be doing which task, etc. So here are my questions:

1. What do I say when they ask me if I have any questions? I know about the position, the firm, the hours, compensation, etc. So what do I ask? This is always a big problem for me.

2. How do I relay my skills to the interviewer without coming across like I’m rattling off a list? For instance: They ask, “What can you bring to our company?” I start to rattle off I’m organized, a quick-learner, blah blah blah. Is there a better way?

3. Why is it that I keep getting the 2nd interview, but no job offer? Most of the places I have interviewed have said they were seeing upwards of 25 people. How can I make myself stand-out?

I’ve followed all the other advice, including sending thank-you notes. Any other suggestions?
