Graduate Programme
Our graduate programme application process has now closed.

Applications for the 2020 Graduate Programme will open in September 2019.

Beginning your journey

Your first week at Three will be all about getting an overview of how we work. You’ll be introduced to life at head office in the heart of Dublin, visit retail stores, and see what makes our Limerick service centre tick. You'll also learn the ins and outs of teamwork on a two-day team building session at a surprise location.


You'll have three eight-month rotations with three talented teams and three managers during the programme (we like doing things in threes). It's a diverse experience, but always links back to your field of study. We're constantly exploring ways of being better connected and we make sure you mix daily deliverables with longer projects around the business to understand this.

#3Grad gives back

Want to make a difference and bring about real change for people? We'll give you the tools to do that. You and your graduate team will work closely with a charity partner on a project that makes the most of your talents. You can find out more about Three’s commitment to corporate social responsibility here.

Training and Development

We don’t think learning should stop after college. That’s why we’ve put together a training and development plan to make sure you have all the skills you’ll need to excel at Three and beyond. You’ll work on daily tasks in your department as well as challenging projects, all with expert mentoring.


You’ll meet regularly with a personal mentor from your directorate’s senior management team. They’ll offer insights on career development, team objectives and goals, and the company as a whole.

Throughout my internship, I’ve created data visualisations using software tools, carried out network drive test campaigns, took responsibility for pre-existing weekly processes, learned how network masts function and realised how data-driven the future really is. Three’s exciting and dynamic environment as well as its friendly, approachable staff made this a very enjoyable experience for me.

I wanted to work in a fast paced and exciting company that is both challenging and rewarding and appreciates its employees, and Three is the place for exactly that! I have learned so much from Three’s Brand and Marketing Communications team. I have enjoyed being part of this team, and having the opportunity to be creative and make decisions. Three has created a culture where I’m excited to come to work every day, to continuously learn and collaborate in a dynamic environment.

I never realised how much of a learning curve Three’s summer internship programme would be for me. Through high-pressure teamwork and event planning, I gained a better understanding of how to communicate accurately, overcome challenges and push myself beyond my comfort zone.

The amount of time and effort that Three puts into the internship programme is second to none, with constant training and development for graduates, as well as real, impactful work planned out for the programme.

Nearing the end of my internship, I was lucky enough to secure a job as a digital marketing executive. Over a year on, I am still thoroughly enjoying being a valued member of the team and looking forward to further career development within Three.
