Hello! I just had my interview with Harvard on Friday, and it wasn't as great as some of my other interviews, but I don't think it went badly by any means. However, on my way out, I said, "I'd love to stay in touch and let you know when the decisions come in. May I add you on LinkedIn?" My interviewer said yes, and after I sent him a thank-you email, I sent him the invitation. The thing that worries me is that he hasn't accepted my request. I know this sounds silly, but should I be worried that he's intentionally avoiding my request? Should I take it as a bad sign of what he's going to write in his review of me? Or is there a rule that they shouldn't add applicants because it might show they're biased towards him or her? Or am I missing another explanation? Thanks!
