I applied online. The process took 2 weeks. I interviewed at 9thWonder (Houston, TX)
Interview
They are really nice people. The interview felt like a conversation, but be prepare to answer specific questions about your resume. My advice is to have examples ready to illustrate the qualities you listed in your cv.
Had an initial phone interview with the HR Director. Then went into the Houston office for an in person interview with a group of other interns. The in person interview took about 30 minutes.
I applied through university. The process took 4 weeks. I interviewed at 9thWonder (Houston, TX) in Mar 2014
Interview
I submitted a resume and cover letter - mentioned my professor who has a good relationship with HR.
They invited me into the office. There were 6 others in the room, and they called us back to meet with HR one at a time. Talking with HR lasted 5-10 minutes.
I passed the HR test, so then I had an interview with my department head. If you've made it to this point, you have the internship. (Assuming you don't clash drastically with your department head).
Interview questions [1]
Question 1
In the first interview, they mostly asked me about my resume qualifications. They want to get a feel for WHERE you'd be a good fit, regardless of what position you applied for. Be open to their suggestions if they don't think you'd be a good fit for where you applied for.
In the second interview, the department head really just wanted to make sure I could handle the role.
