You send in your resume to one of the hiring managers and then they call you schedule a date. One face to face interview with the HR manager. It was the standard behavioural questions like "Name a time you had to overcome a challege..etc". More of a conversation and less of an interview. Dress code was semi-formal, I did not wear a suit. Afterwards you had to fill out a test to see if you math skills were to par. Overall, easy interview.
