Goodbye College, What I Wish I Knew (Data Science Edition)
Published 2026
Who am I? I'm Yousef, and I'm graduating with a Bachelor of Science in Data Science from UNC Charlotte. Now that I'm finishing up, I feel like I should pass down some of the things I learned, the stuff no one really tells you, so maybe you can struggle a little less than I did.
Don't rush college just for the sake of it
Unless you've got a very specific reason (like the GI Bill), there's no real need to rush through college, especially when you're young.
I live in Charlotte, and in 2023 I went to Greensboro for a door-to-door sales job. It was supposed to help me grow and learn new skills. It did, but it also took me a whole semester to realize I was being taken advantage of.
I made about $5,000 total… and yeah, there were days I struggled to eat.
But at the same time, I met a lot of people, learned a ton, and had experiences I'll never forget.
So I don't regret it, but I also learned: don't rush into things just because they sound like "growth."
If you want more out of life, join group-based activities
If you want to maximize your experiences in college, get involved in something social.
For example, I go to the gym, which is great, but it's usually solo or with a small group. If you really want to expand your circle and have more experiences, do something like joining a volleyball group or any community-based activity.
The more people you interact with, the better.
- You build connections
- You improve socially
- You honestly just become a happier person
2.1 Networking
Networking Matters More Than You Think.
Whether you like it or not, networking plays a major role in your professional life.
Look around at the people in your classes. The students sitting next to you today will eventually become analysts, engineers, managers, founders, and team leads. Many of them will build successful careers in the same industry you're trying to enter.
With that in mind, building relationships with your peers is just as important as building technical skills.
A surprising number of job opportunities come through personal connections. That's why it's worth making a genuine effort to get to know people. Learn their names. Remember a few details about their lives. Be someone others enjoy talking to and spending time with.
This ties directly into the previous section about group activities. If you play volleyball at the campus gym every week, don't just show up and leave. Get to know the people there. Become part of the group. Build real friendships.
You never know where those relationships will lead. The person you meet today could recommend you for a job years from now, introduce you to a future business partner, or simply expose you to opportunities you would have never found on your own.
One of the hidden benefits of college is the network you build while you're there. Take advantage of it.
Specialize outside of data science
If you're in data science or computer science, here's the reality: you're competing with everyone.
To stand out, you either become insanely good technically, or you combine your skills with another field. I recommend the second option.
Pick an industry, even if you're not passionate about it, and learn it.
- Healthcare
- Banking
- Supply chain
- Energy
For me, it was supply chain. I didn't start with a passion for it, but my curiosity got me an internship as a Supply Chain Analyst. During that time, I earned a Lean Six Sigma Yellow Belt certification.
Now, when I apply to roles, especially in manufacturing or operations, I have a real advantage over someone who just has a degree. It also opens more doors beyond "data scientist," like analyst or even buyer roles.
Projects matter more than you think
Projects are everything. Start by learning Git and using GitHub. That's where you'll store and showcase your work, and most companies expect you to know it.
Your first project should honestly be simple.
- Build a basic website
- Host it (Cloudflare works great)
- Use it as your portfolio
- Include: LinkedIn, Email, GitHub, a projects section
From there, build projects based on your specialization.
-
1
Scrape commodity price data using Python
-
2
Automate it daily with GitHub Actions
-
3
Store it in a SQL database
-
4
Build a dashboard (Streamlit works great)
That kind of project directly translates to real-world work.
If you don't know what to build, talk to professors or look online (Reddit, forums, etc.).
Build a personal brand (without being fake)
When I interned at ABB, I met someone named Nakyah. She was great at her job, but what really stood out was her presence. People naturally went to her for help.
Why? Because she built a strong personal brand by talking to people, listening to their problems, and offering thoughtful input. That made her incredibly valuable.
Now, your personal brand should be personal. Don't fake who you are. (Unless you're genuinely unlikeable… then maybe adjust a little.)
If you're introverted, you don't have to force it. Just make small talk, ask about people's work, and show genuine curiosity.
5.1 Your online persona should reflect the personal brand
Your website should communicate the kind of person you are. Generally speaking, you want one main color and two supporting colors. The colors you pick aren't about picking colors you like, but picking the kind of vibe you want to have.
The colors of my choosing are #6c63ff, #ff7ac0, and #5ed0bd. These are really cool colors that have effects on the reader.
Lighter colors have a more soothing effect to look at, even if you pick an aggressive color like red.
Keep your brand consistent. A doodle is the best way to communicate "I'm a person", which is what recruiters are dying to see.
5.2 Have an Email Signature
This is the most optional part of this entire reading. The whole point of "building your personal brand" is to be your own company as a human. This is kind of a cherry on top of all that.
Every company has an email signature. You don't need a custom email, but a simple email signature will look more professional than not having one, and does much better than ending an email with just "-insert name here."

Next Generation
If you're a freshman, do this early: join a club related to data science or whatever field you're interested in. Then find a mentor.
You can find one through your club or your university's career center. When choosing a mentor, make sure you actually like them and that they're open-minded and willing to help.
- You have someone in the industry to ask real questions
- You get guidance on what actually matters
- You hear about events, opportunities, and paths you wouldn't find on your own
- It saves you time, and mistakes
If you're a senior, become a mentor. Pick up a mentee.
- It makes you more hireable (you can demonstrate leadership)
- It gives you early management experience
- It forces you to understand concepts more deeply because you're teaching them
Plus, it just feels good to help someone avoid the same mistakes you made.
Use LinkedIn… but don't overthink it
Make a LinkedIn. You don't need to go crazy with it. Just post your highlights.
- New job
- Internship
- Projects
- Capstone
- Competitions
That's enough. There's a whole world of "LinkedIn optimization" out there… and yeah, it probably works. But personally? I don't enjoy it. Do as much as fits your style.
Final Thought
College teaches you a lot, but not always what actually matters. So if you take anything from this:
- Don't rush
- Get experiences
- Specialize smartly
- Build real projects
- Be someone people want to work with
Good luck. You got this.
