"An interview with our Divemaster and Instructor Trainee Joshua (Germany)".
One of the questions I was asked most before starting my Divemaster internship was:
"So... what do you actually do all day?"
Before arriving in Costa Rica, I honestly wasn't sure either.
I imagined I would spend every day diving, swimming with sharks, and enjoying life in paradise. While there was certainly plenty of amazing diving, I quickly discovered that a Divemaster internship is about much more than simply logging dives.
Looking back, I'm glad it was.

Those three months gave me a realistic picture of what it's like to work in the diving industry and helped me develop the skills and confidence I needed to become a professional.
Every Day Starts Early
Life at a dive center starts well before the guests arrive.
Our mornings usually began with preparing equipment, checking cylinders, loading the dive boat, and making sure everything was ready for the day ahead.
At first, these jobs seemed like simple chores.
After a few weeks, I realized they were teaching me one of the most important lessons in professional diving: Preparation is everything. A successful dive begins long before anyone enters the water.
Learning From Real Dive Professionals
One of the biggest differences between recreational diving and professional training is that you're constantly observing experienced instructors and Divemasters.
Every briefing, every customer interaction, every decision on the boat becomes a learning opportunity.
I learned how to organize groups, explain dive plans clearly, help nervous divers feel comfortable, solve small problems before they became big ones, and adapt plans when conditions changed.
These are skills that simply can't be learned from a textbook.

Assisting Courses
One of my favorite parts of the internship was assisting on dive courses.
Instead of only focusing on my own development, I had the opportunity to help new divers build confidence underwater.
Watching someone complete their first underwater skills or seeing the excitement on their face after earning a certification reminded me why I fell in love with diving in the first place.
It also confirmed that becoming an instructor was the right next step for me.
Every Dive Is Different
One of the reasons I chose Costa Rica was because of the Pacific Ocean. The conditions change constantly.
Some days the water is calm with incredible visibility.
Other days there are stronger currents, lower visibility, or different sea conditions.
At first this challenged me.
Eventually I realized these changing conditions were making me a much better diver.
Every dive required observation, planning, flexibility, and teamwork, exactly the qualities employers look for in a professional Divemaster.
It's Not Just About Diving
Something that surprised me most was how much time was spent learning everything that happens outside the water. During the internship we participated in professional workshops covering equipment maintenance, customer service, sales, dive briefings, CV writing, and preparing for a career in the dive industry.
We even received professional headshots for our CVs and learned how to apply for jobs around the world.
Those workshops gave me confidence that I wasn't just becoming a better diver, I was preparing for a career.

Life at the Divemaster House
Some of my favorite memories actually happened after the diving was finished.
Living with other Divemaster candidates meant there was always someone to share stories with, practice skills, plan adventures, or simply relax after a long day.
People came from different countries and backgrounds, but we all shared the same passion for diving. It didn't take long before strangers became close friends.
Becoming Part of the Local Community
Another thing I really appreciated was that I didn't only spend time with other international trainees.
The local Costa Rican staff were incredibly welcoming, and there was a genuine sense of teamwork between everyone.
Whether we were preparing boats, chatting after work, or enjoying social events together, I felt like I experienced a side of Costa Rica that many tourists never see.
That made the experience feel much more authentic than simply visiting for a holiday.
More Than Training
Throughout the internship there were beach BBQs, pool parties, beach Olympics, dinners, and other social events that brought everyone together.
Those moments created friendships that I know will last long after my internship.
When my family and friends came to visit, it was wonderful to see them welcomed just as warmly as I had been.
Some went diving, others joined snorkeling trips where they saw turtles, rays, and even humpback whales, while others enjoyed an ATV and zipline adventure organized by the dive center.
Seeing everyone enjoy themselves reminded me that diving communities often become extended families.

The Biggest Lesson I Learned
When I first arrived, I thought becoming a Divemaster was about improving my diving skills.
By the end of the internship, I realized it was about much more.
It's about leadership.
Responsibility.
Communication.
Problem-solving.
Helping people overcome their fears.
Working as part of a team.
And making sure every diver returns to the boat with a smile.
Those are the skills that transform someone from a recreational diver into a true dive professional.
My Advice to Future Divemasters: Don't choose an internship based only on price or the number of dives you'll complete. Look for a program that gives you real responsibility, mentorship, and professional development. Those are the experiences that will prepare you for a successful career in diving.
Looking Ahead
Finishing my Divemaster internship wasn't the end of my journey.
In fact, it felt like the beginning.
That's why I've decided to continue with my SSI Instructor Course in Costa Rica. I want to keep learning, gain real teaching experience, and continue developing the skills that will help me build a career in the diving industry.
If you're wondering whether a Divemaster internship is worth it, my answer is simple:
If you choose a program that gives you real hands-on experience, challenges you, and helps you grow both personally and professionally, it may become one of the most rewarding experiences of your life.
In my next blog, I'll explain why I chose SSI for my professional training, what I liked about the system, and why I believe choosing the right dive center is just as important as choosing the certification agency.
