My son is a Senior studying Mechanical Engineering at the University of Texas. I talked with him over the break about networking and using LinkedIn.

We usually talk about LinkedIn as a tool for job hunting. But for college students, it’s much more powerful than that.

It’s a career-long relationship engine. And the earlier you start building it, the more advantage you’ll have over everyone else.

Networks Compound Just Like Money

One of the most misunderstood parts of career development is timing. Most students wait until junior or senior year to get serious about networking… which is like starting to invest at 45 and hoping compounding interest saves you.

Connections made in college are incredibly valuable because they age well.

Those classmates?

They’re going to become engineers at marquee companies, startup founders, executives, innovators, and hiring managers.

Those professors?

They’ve spent decades building relationships with industry leaders.

Those coworkers from internships?

They’ll scatter into incredible organizations.

When you start early, you build:

  • A broader network

  • A stronger reputation

  • Relationships that exist before you need something

That’s where real opportunity lives.

Hiring Today Is Driven by Relationships

Whether we like it or not, a large percentage of hiring isn’t happening because candidates applied online. Recruiters and hiring managers increasingly rely on:

  • LinkedIn searches

  • Referrals

  • Warm introductions

  • Visible proof of professionalism

A student who:

  • Has a credible profile

  • Shows projects or internship experience

  • Is connected to people in their field

…already stands out from 90% of their peers.

LinkedIn Isn’t Just for Job Seekers

For students, LinkedIn is also:

  • A learning platform

  • A discovery tool

  • A professional playground

  • A way to observe how leaders in their field communicate

They can:

  • Follow companies they’re interested in

  • Learn what skills matter

  • See career paths unfold in real time

  • Reach out for informational conversations

  • Stay in the loop on industry trends

It’s a front-row seat to their professional future.

What Students Should Actually Do on LinkedIn

If you’re a college student (or parenting/mentoring one), here are practical steps to take:

Connect Intentionally

  • Classmates in your program

  • Professors and administrators

  • Internship coworkers

  • Managers and mentors

  • Guest speakers

  • Alumni you meet

Build a Simple, Credible Profile

  • Professional-looking photo

  • Clear headline (“Mechanical Engineering Student | Interested in Robotics & Product Design”)

  • Short About summary

  • Projects, internships, or accomplishments listed

Engage Occasionally

You don’t have to post every week. But like, comment, congratulate others, and occasionally share meaningful milestones.

This builds professional visibility without feeling artificial.

A Word of Caution

LinkedIn is not Instagram.

It’s not the place for drama, ranting, or sarcasm. What you post can follow you for years. Treat it like the professional tool it is.

Final Thought

If you’re a college student, your network is going to matter for the rest of your career. The people you sit in class with, learn from, and work alongside will shape opportunities you haven’t even imagined yet.

Start now.

Build relationships early.

Invest in your future network long before you “need” it.

Your future self will be very thankful that you did.
