Q: How many internships should I do while in college?
A: As many as you can! I recently met a student who did 5 internships. Personally, I did three while in college. One of my recent graduates did one for over 9 months, and landed a permanent job with that company.
If you can get a company to hire you (even for just a few weeks) to be an intern, it is something to put on your resume, and will follow you wherever you go.
One question I often get is “where do I find an internship?” Sometimes it’s just a matter of reaching out to people, and telling them you are a college student looking to gain some knowledge while sharing your skills; just that alone will open doors for you.
