First of all, part-time jobs generally settle wages on time or on a daily basis, which can bring the fastest sense of satisfaction and accomplishment, and also provide college students with the motivation to make money.
However, internships are generally unpaid or low-paid, and college students who are purely aiming at accumulating work experience generally cannot get real happiness from their hearts, so it is difficult to stick to a job.
Secondly, the scope of part-time work is wide and there is no limit. College students can try different jobs at the same time and tap their interests and abilities.
However, the internship can only be a fixed job in the end. Maybe the job you choose is not what you really like, which will not help you in your future job search.
Finally, compared with internship, college students have lower threshold for part-time jobs and higher salary, which can not only accumulate salary experience, but also meet different people, which is helpful for college students to get close to the complexity of society.
However, internships are generally in a relatively stable environment, without any challenges and passions, and you can't see many novel things.
In short, the choice that suits you is the best, and the scenery of others is not your own strength.
