You will likely be offered a contract outside of the Match which means you need to batch your interviews since these offers often expire within a week. These offers outside of the SF Match are called match exceptions, and programs are allowed to offer them to any candidate staying for more than 2 years of training. Although they were designed for internal candidates or anesthesiologists staying for multiple years (CCM + cardiac), programs can and do offer them to fill their EM spots since those spots are for 2 years.
For example, I had a general idea of what were my top 2 programs based on faculty profiles, research interests, etc. when I submitted my SF Match profile, but wanted to use the interview before making a final decision. I scheduled the interview for my first choice in Feb and second choice in March. However, my top choice offered me a position a week after my interview, and the offer expired before I could attend my second choice interview. In fact, I kept in touch with a couple of the other EM applicants that I meet on the interview trail and all of us were offered positions ahead of the Match.
Also, keep in mind that many programs have 4 or more slots per year, but only 1 or 2 are funded and ABA approved for EM applicants. That means that the competition is very different for EM and anesthesia applicants but most of us eventually landed somewhere.
Finally, have fun. Enjoy meeting the other applicants. They are you colleagues and medicine is a very small world.
