tl;dr: yes, you’re ready.
If you’re asking whether it’s a good idea to apply, simple answer: yes! There’s roughly no downside to sending your resume out to as many companies as you can find who are accepting applications for entry level internships, other than spending the time to do so. The worst case is that you get a rejection or never hear back. This holds true for all application levels, from high school to super duper experienced.
Applying to jobs is itself a valuable skill to practice. Spend time on your resume to make it showcase what makes you shine: projects, coding experience, extracurricular activities, whatever you have. When I was fresh out of high school I included my summer camp counseling job as well as my coding projects and classes. Make a few templated cover letters you can base individual company applications’ cover letters on. Always submit a cover letter if they ask!
If you’re asking what skills you should have, I think you should apply regardless of where your skills are because the best way to get good at the job application process is to go through it! Just like coding!
But, in addition to the resume and cover letter stuff, these are things that are really good to practice:
- Coding projects: they demonstrate your ability to tackle bigger problems
- Group projects: coding in industry is almost always about working effectively with other people!
- Explaining one of your coding projects to a professional: be descriptive yet pithy (what a challenge!), DRY, KISS, and make yourself seem confident & smart
Getting people who have already gone through this process to help you is super useful. If you haven’t yet, I’d recommend reading How to Win Friends and Influence People. Not 100% applicable here -there are probably better books for interviewing- but just a really good read on interacting with others .
If you’re asking whether you’ll be successful, a bit more nuanced. First of all, see earlier paragraph on experience . The market is a lot smaller for entry-level positions for students who haven’t yet hit university. I personally couldn’t find anything over the summer before my freshman year. This is part of why it’s good to apply as widely as possible: try for things out of your comfort zone. You never know! (and you can always reject them if you hate them after all)
I’ll also note that many (most?) CS university students don’t come in with CS-specific internships before their freshman year, and many don’t get it until their sophomore or junior years. That’s totally fine! But it’s awesome and a nice leg up if you do land one.
