Received an email to set up a phone interview. During phone interview, the supervisor for the position gave an overview of the position and then began asking about my qualifications. The interview lasted about 45 minutes and I then followed up via email to set up an in-person interview.

The interview process is long and slow overall. Went through about 5 phone interviews in a span of about 4 weeks. First phone screening was with HR, then hiring manager, then a bunch of other senior engineers and finally an on-site interview with 4 different engineers (some of which I've spoken to on the phone before). Still a couple of weeks to wait for the approval from upper management after the unofficial acceptance from the hiring manager. A background check was also performed.
