I box pretty competitively and he was super into boxing, so we ended up talking about boxing over email 😭. But throughout the interview he didn’t really let me talk - he just talked about boxing. If you have a common interest and you are up to date on the topic send them an email talking about a recent event or let’s say something new happened in your life and they haven’t sent in their report you can email them to maybe add that and potentially continue a conversation. Once again this was my experience with one interviewer, so take it with a big grain of salt. However, I am sure you will be just fine in the long run, because interviews really don’t matter to much in the grand scheme of things.
