Harvard Business Publishing interview questions

I submitted an application and was contacted by a recruiter a week later. (I should disclaim that a friend used to work here, so I think that's why I heard back so quickly.) The recruiter scheduled a call for the following week. The call lasted about 30 minutes. The recruiter was pleasant to speak with and asked general questions (why do you want to work here, how does your experience relate, etc.), and said she would follow up with me about speaking to members of the team this position worked with. I sent a thank-you message the next day, and then... nothing. Two weeks later I sent another follow-up, and then a week after that, I got a brief e-mail saying that they had decided not to move forward with my candidacy. No explanation why. By that point, I was frustrated and less than impressed with the process (even though the recruiter had been pleasant on the phone), so it did not feel worthwhile to try to follow up again.
