For paid positions, you fill out an application online. They call you to schedule an interview. The first part of that interview is a written portion of questions, the second part is the typical face to face interview with individuals related to your specific position. The verbal portion isn't too long. For internships, you fill out an online application, they call to schedule an interview, you are interviewed (usually 30 mins to 1 hour), and you get a call back afterwards letting you know if you are offered the position.
