I was referred by a friend who is an employee. The process went as follows. I took significant time to review and update my resume. Then I submitted it and received an email from the hiring manager for a phone interview. The phone interview went well and was basically just a rehash and further explanation of my projects and accomplishments during the current position I was in. Next I received an email asking me for an in person interview. The interview was behavior based and lasted about an hour. Some impromptu testing or questioning on technical subjects may occur to demonstrate competence.
