Go out, meet people, talk to them. Note what works and what doesn't.

Most friendships are made by doing something that puts you in proximity to the same people repeatedly. Go join (or start) a pickup sports team. Or a reading club. Or a run club. Or hang out at a bar on the same evening each week. Find something that aligns with your interests. Do it with other people. If they invite you to grab dinner or go somewhere afterwards, go along and keep talking.

The goal isn't to interview people.
