What is good enough in today's competitive working world?

Hi, I am a Double major in Applied Math and Statistics and a minor in CS, currently a junior with a cumulative GPA of 3.5 for the past 4 semesters.
Is that good enough to land me a job(Paid internship) this summer ? I really have no clue as to what is good anymore.

Your major alone and your GPA don’t land you a job - experience lands you a job, things like the internship you are seeking.

Lots of students with a 3.5 and two quantitative majors get internships, but getting one is about more than just your GPA. What else do you do on campus? Are you a good problem-solver? Independent? For most internships you’ll have to interview and maybe demonstrate some skills.
