two rounds of interview, first HR phone screening, next hiring manager phone interview. next HR called and gave a verbal offer. After I accepted the offer, then they did background check and drug test.

Applied online, was contacted by HR to set up an interview a few weeks later. Initial interview with HR is approx 30 mins and covers mostly general HR type questions (do you need sponsorship, are you willing to relocate, etc). After HR screens you, your resume and their notes are passed on to the specific hiring manager. The last and final interview with the hiring manager are either in person or via skype.
