After applying online, you will receive a call from one of the HR reps to have an informational interview about the role. You will also answer the generic interview questions that you get anywhere.
Assuming you are a good fit, they will have you take an Omnia test (intelligence indicative test). If you get a high enough score on that, you will be called in for an interview with the hiring manager(s) of the department (in sales, this could be one or more of about 4 different people).
Depending on who you interview with, you may need a second interview with the head of the department.
Turnaround on an offer is pretty quick.
