Two phone screens, each consisting of some technical questions and then answering questions I have. Took 2 weeks after each phone screen for a reply about next steps, 1st reply was to set up 2nd interview, 2nd was informing me of rejection. Contact with hr/recruiter was very impersonal, I think every email I got was a form email, and I didn't get any feedback about why I was rejected - I got all the technical problems right.
