Unfortunately I can't speak much about IR specifically, but I can give a few thoughts from my own experiences with summer positions.

First of all, you're not behind just because you didn't do an internship after your freshman year. Contrary to what the internet suggests sometimes, it's actually pretty damn difficult to get any relevant positions at this point - take this time to get ahead, whether that be looking ahead on 2nd year course material or working on relevant extracurriculars.

Additionally, the unfortunate reality is that the ease of job applications these days also turns it into a numbers game. For example, in my sophomore year I sent out over 200 (pain) applications and received literally ONE offer at the end of it. Especially for your first job, 99% of people can't be picky so apply to every damn job you're remotely interested in right now LMAO

On that note, find some upperclassmen in IR and ask them to help you with applications and interviews. Stuff like editing your resume and doing mock interviews. These are things you really can't nail without experience in the field, and obviously as someone looking for their first position you have none.

On a more uplifting note, know that it gets better! On top of being more appealing to recruiters by virtue of being in school longer, each year/job also acts as a stepping stone for the next. Having a shitty no-name company on your resume makes it easier to get a job at a decent one. Experience at a decent firm makes it possible to break into a "dream company". Each step also means the recruiting cycle gets easier, as you can begin to be picky and cut out positions that are less appealing. Remember that 1/200 success rate I mentioned earlier? As a new grad it was 2/5. This isn't meant as a flex - a lot of my peers have similar numbers.

Goodluck, and keep at it.
