LECOM-B will send you a postcard in the mail when everything is in hand-- then they offer an interview, but not until. In fact, they will often send you a post card updating your status (recommendations received, etc.) after a few weeks to let you know if something is missing. That happened to me. One of my professors was pretty slow in sending them out, but I wouldn't have known it if they didn't let me know.
Good Luck!
