How a Two-Week Internship Turned Into a Real Business Role

How a Two-Week Internship Turned Into a Real Business Role
AUTHOR
Marko Veruovic

I’m Marko Veruovič, a high-school student, and this is my true story about where a school internship took me in my career. My collaboration with Etnetera Flow continued even after the internship ended, and gradually deepened as I transitioned into a part-time Junior Marketing & Sales Analyst. Let’s take a look at how it all started and what one bold message can kickstart.

From Inspiration to Action

November 2023. High school students are looking for inspiration at the Můžeš podnikat (You Can Do Business) event, and Etnetera Flow is presenting a talk on how artificial intelligence is changing the world of sales and marketing. I’m sitting in the audience. I leave not just with enthusiasm, but with a determination to reach out to this exact company.

A few days later, I write to the Flow team:

“We have mandatory internships coming up. Are you considering any new additions?”

And it worked. The team at Flow said yes.

In May, I stood at the company entrance as an intern for a two-week placement, arriving with a clear goal. I wanted to experience firsthand how a mobile app development company really works, and ideally contribute to something meaningful (even with the risk that I might mess something up).

That is exactly what happened. The two-week internship turned out to be a ticket into the business world. I settled into the Flow team quickly, and it was clear that I was eager to work and learn.

Project Horizon and Mission Denmark

Right from the start, I was thrown into the deep end and involved in the Horizon Project. The goal was ambitious: supporting Etnetera Flow’s entry into the Danish market.

My role quickly took shape. I supported mainly marketing and business research that served as key groundwork for the marketing and sales team.

But it wasn’t just about Googling the competition. I was entrusted with working with modern AI-powered tools such as Profound (Generative Engine Optimisation), Coherta (a Danish lead-generation tool), and the internal App Store Scrapper.

The App Store Scrapper proved to be a powerful tool for my work. It allowed me to bulk-download reviews and data from mobile app stores like Google Play and the App Store. This data made it possible to go much deeper in my analysis and recommend where to focus our efforts. I looked across a broad spectrum of the Danish market, from fintech and banking to retail, insurance, beauty, and e-commerce. Simply put, I mapped out anything that had an app and real users.

Thanks to this data, I could identify opportunities and spot apps that were ripe for redesign or clearly needed tech help. We monitored which apps were performing best, why they were successful, and used these insights for further business decisions. 

For example, I analysed over 4,000 reviews of Danish banking applications. I discovered what local users complain about, which features they are missing, and where banks are falling short. This kind of insight is worth its weight in gold for both marketing and sales.

A Day in the Life of an Intern

Every day at Flow looked a little different, but the structure that kept me on pace stayed consistent:

08:30 – Coffee and Quick Sync
A short sync with the sales and marketing team: who is handling what, and where I can help.

09:00 – Deep Dive into Project Horizon
Working with Flow Scrapper, market research, and competitor analysis.

11:30 – Consultation with a Mentor
Feedback on progress and tips on better resources or approaches.

13:00 – Lunch & Networking
After lunch in the coworking space and discussions with colleagues ranging from developers to leadership, I return to work.

14:00 – Preparing Outputs
Structuring insights and creating management summaries with key findings.

16:00 – Day Review
Reviewing findings with leadership, adding missing data, and discussing how the insights could be applied in practice.

The feeling that my work didn’t end up in a drawer, but actually influenced the company’s strategy abroad, was priceless.

AI Is a Tool, Not an Answer

During the internship, I realised that while tools like ChatGPT or Perplexity can do a lot, you can’t trust them blindly. AI likes to make things up occasionally, and while it’s a great help, every statistic and claim has to be verified.

“I learned to treat AI as a partner, but the responsibility remains mine.”

Prompting, working with context, and verifying sources are skills you won’t learn from a textbook. But once you master them, you gain a huge advantage.

From Internship to Long-Term Collaboration

After the first internship, I came back for a second round. I arrived with the same desire to learn, and that led to an offer for long-term collaboration. Today, I work at Flow as a part-time Junior Sales & Marketing Analyst. At the same time, I’m leveraging everything I learned to launch my own marketing agency. The skills I gained during research and presentations are ones I now use every single day.

Internships at Etnetera Flow aren’t about filling a seat. They’re for people who want their work to have real impact, want to see what business looks like in practice, work with tools not typically taught in school, and meet mentors who genuinely care about their growth.

I’m one of them. But I wasn’t the first, and I won’t be the last. Alongside classic internships, Flow also runs a mobile academy where students from all over the Czech Republic get to know the world of mobile apps and real business firsthand.
