I applied online through Harvard's online application system. I received a phone call one week after application submission, from the position recruiter, asking to schedule an initial 30-minute phone interview. The recruiter scheduled the interview to occur exactly one week from the time of this scheduling conversation (i.e. two weeks after application submission). While I declined to continue after the first round phone call, the recruiter had indicated subsequent steps would involve a phone or in-person interview with management and then a phone interview with HR.
