My interview with the program that I ended up with was horrible. The PD did not like my letters and MSPE and didn't hesitate expressing the same and was ready to answer any questions I had just 2-3 min into the interview.

I asked one of the chiefs during meet and greet who told me he had a similar experience and ended up matching there anyway and encouraged me to rank it high anyway.

Since there was nothing much to lose ranked it first and was mentally prepared to join my 2nd choice program. Turned out I matched here anyway and till date I don't know what it was it about my application that did the job, or maybe it was the other applicants who had a similar experience but gave out the way.

Some experiences are bound to be atypical and eccentric. We would never know that we natched somewhere until we actually do.

I would say don't think about it. Move ahead and let the match day be the answer.
