As a master’s student in Electrical Engineering at RWTH Aachen University, I had the opportunity to complete a six-month internship at Qualcomm in Cork, Ireland, supported by the Erasmus+ Internship Programme. My goal was to gain practical experience in my field while improving my language skills and experiencing life abroad.
1. Application/Finding an internship
I did not specifically look for an internship in Ireland at the beginning. My main aim was to complete an internship during my master’s studies in a country where English or Spanish is spoken, so I could improve one of these languages. Going abroad was a priority for me. I had heard great things about Ireland from two friends who had previously lived and worked there for half a year, so Ireland quickly became a strong option.
I applied directly via the Qualcomm careers website for an internship position in their Cork office. After completing several interviews, I was fortunate to be offered a place.
2. Accommodation & Living expenses
Shortly after receiving my internship offer, I began searching for accommodation. I was surprised to find that rental prices in Cork were quite high, especially considering the condition and furnishing standards of many of the available options. Fortunately, I was later informed that the company provides shared housing specifically for interns. I was able to rent a furnished 12 sqm room with a private bathroom in a four-person shared house located very close to the city centre. The house included a shared living room, guest toilet, and communal kitchen. The rent was €1000 per month – a flat rate that, as I understood, applied to all interns living in company-provided housing.
Grocery prices were similar to those in Germany. However, prices for personal care products were significantly higher, and alcoholic beverages in supermarkets were extremely expensive. Prices in pubs for a pint of beer ranged between €4.40 and €6.70 – quite steep, though not unheard of compared to places like Cologne. Eating out at restaurants was only slightly more expensive than in Germany.
For baked goods, Lidl offered a self-service bakery section very similar to the ones in Germany, with comparable prices. If you’re looking for high-quality bread, the English Market in Cork is a good place to go – though the prices there are significantly higher.
3. Everyday life/The internship
During my internship, I worked 37.5 hours per week as a Timing Engineer at the company. The office had a very international environment, with interns and colleagues from all over the world. This made for a dynamic and collaborative workplace, where English was the primary working language.
Although I’m unable to go into detail about my specific responsibilities due to confidentiality agreements, I can say that the experience significantly strengthened my technical and analytical skills. I also had the opportunity to work with state-of-the-art tools and contribute to real-world projects within a professional R&D environment.
Regular meetings with my supervisor ensured that I received consistent guidance and feedback, and I always felt well supported by my team. In addition, Qualcomm offered internal learning opportunities such as tech talks and knowledge-sharing sessions, which broadened my perspective on current trends and technologies in the industry.
The office was located within walking distance of the city centre, which made commuting very convenient. I had heard from many others that buses could be unreliable, but since I didn’t rely on them, I can’t confirm this personally.
4. Free time/Tips
Cork is a relatively small city, so you can explore most of the main sights in just a few days. Highlights within the city include Elizabeth Fort, Saint Fin Barre’s Cathedral, the University College Cork (UCC) campus, and the historic Cork City Gaol. A highly recommended walk leads from the city centre to Blackrock Castle, along a newly developed riverside promenade. On the way there or back, it’s definitely worth stopping by the Marina Market, a large indoor street food hall offering international cuisine and a lively atmosphere.
Cork also boasts a vibrant and active pub scene, with events such as pub quizzes, live music – from traditional Irish tunes to international classics – beer pong tournaments, and more. Especially on weekends, there’s always something happening.
When the weather is good, relaxing outdoors is easy. In addition to Fitzgerald Park, Cork Lough and St. Patrick’s Hill are great spots to lie on the grass and enjoy the sunshine.
For short trips just outside of Cork, the harbour towns of Kinsale (about 1 hour by bus) and Cobh (25 minutes by train) are highly recommended. Both offer beautiful coastal views and a pleasant atmosphere for day trips.
There’s also a WhatsApp group and Instagram page (corkinternationalstudents) specifically for international students. These platforms help organize a variety of events in the city, such as parties, pub crawls, karaoke nights, and more. They also arrange affordable tours to Irish landmarks like the Cliffs of Moher, cities such as Dublin or Galway, and scenic hikes to places like the Ring of Kerry or Coumshingaun Lough. The people involved are very welcoming, and it’s a great way to make new friends – including students from UCC.
Another cultural highlight is attending a match at the GAA stadium to cheer for Cork in traditional Irish sports like Hurling and Gaelic Football. When Cork reached the provincial finals and even the All-Ireland semi-final and final in Hurling, the whole city came alive with celebration and watch parties.
If you’re a fan of other sports, you can also catch international football matches at pubs like The Woolshed, which even streams the German Bundesliga – perfect if you want to see Borussia Dortmund win a match!
5. Conclusion
I truly enjoyed my time in Ireland. I had the chance to meet many friendly and inspiring people and gained valuable professional experience. Following my internship, I’ll be moving back to Cork to work full-time for the same company. This internship was an incredibly rewarding experience both personally and professionally.
My Research Stay at UC Berkeley
- PhD Candidate for Electrical Engineering
- USA, Berkeley
- University of California, Berkeley
- 05/2025-08/2025
- Preparation and organization of the stay:
I am currently in my final year of my PhD at the Center for Ageing, Reliability and Lifetime Prediction for Power Electronics and Electrochemical Systems (CARL), RWTH Aachen, where I work on analyzing the aging mechanisms of batteries using experimental and simulation-based data. Battery research is highly interdisciplinary, combining knowledge of electrochemical processes, experimental setups, engineering, and data analysis. Spending part of my research abroad had always been very important to me, as it offered the chance to gain new perspectives and access complementing expertise for my research. The energy, controls, and applications lab (eCAL) at UC Berkeley, with its expertise in algorithms, lifetime analysis, and data-driven methods, complemented my background and offered the expertise I needed for my analyses. To prepare for my time there, I organized the battery aging measurements I had started at RWTH Aachen so that they could be analyzed once I arrived at the lab. A professor at my institute from RWTH Aachen put me in contact with my host supervisor.
Organizing the logistics of a research stay in the US can be challenging. Finding accommodation in Berkeley on short notice was not easy, so I opted for an Airbnb, while shared apartments or nearby cities like Oakland offered more affordable alternatives.
- First steps after arrival in host country:
By chance, my first day at UC Berkeley coincided with the annual eCAL retreat, where we went lawn bowling and had dinner afterward. It turned out to be the perfect way to meet the whole group in a relaxed setting and to get to know the PhD students right away. Everyone was very welcoming, and a few of them gave me a tour of the lab. I also met my host professor in person that day, which made it easy to settle in and feel like I could start my research stay right away.
- Academic experience:
eCAL had the feel of a close-knit group: about ten PhD students worked under the supervision of my host professor, supported by a handful of bachelor’s and master’s students. The culture and PhD process at UC Berkeley was noticeably different from what I was used to in Germany. At RWTH Aachen, PhD students often supervise theses and work closely with student assistants, whereas in Berkeley the emphasis was much more on individual projects and dissertation work without relying on large infrastructure and equipment. This meant fewer administrative and organizational duties for the PhD students at UC Berkeley, allowing researchers to focus deeply on their own topics. Each environment had its own strengths and weaknesses, and this exchange gave me the opportunity to integrate the strengths of the US PhD system into my work at RWTH Aachen.
The lab’s relatively small size made it easy to settle in and even though the students were spread across different campus buildings, communication was open and effortless. eCAL was also highly international, with students from a wide variety of cultural backgrounds. This diversity enriched our exchanges, blending technical discussions with cultural perspectives and insights into PhD programs.
- Financing:
The cost of living in the US, especially in the Bay Area, is quite high, covering groceries, leisure activities, and daily expenses. Fortunately, I lived close to a Trader Joe’s, which offered relatively affordable groceries. Getting to San Francisco on the weekends was very convenient thanks to the BART train, while within the city, buses and the metro were the main public transport options. For trips outside the Bay Area, having a car is essential. Renting a car in the US is comparatively affordable, but it requires a credit card.
- Leisure:
Berkeley itself is a relatively small city in the East Bay, and since my stay took place during the summer semester, both the campus and the city were fairly quiet. Overall, I really enjoyed Berkeley and San Francisco as the area has a lot to offer, both culturally and culinarily. I visited Alcatraz, explored several exhibitions, and had excellent food in Chinatown and Little Italy. One thing to keep in mind, though, is the microclimates in the bay area: it can quickly turn cold, windy, or foggy.
California’s landscapes are incredibly diverse, and it is the US state with the most national parks. Many of them are accessible from the bay area, though usually a car is necessary. During my stay, I was able to visit Yosemite, Sequoia, Redwood, and Death Valley National Parks, each was impressive in its own way. I was particularly fascinated by how different the scenery can be within a single state: from the forests of Redwoods and Sequoias to the dry, hot desert landscapes of Death Valley.
- What added value did the stay have for my career prospects?
My research stay abroad was an important step for my professional development. It allowed me to work in an international research environment and gain insights into different academic cultures and PhD systems. I strengthened my expertise in advanced battery data analysis and honed my ability to work in interdisciplinary, multicultural teams. Global issues like climate change can only be addressed collectively, and this experience highlighted how much progress depends on collaboration across borders and disciplines.
- To what extent does my stay abroad have a sustainable character?
My stay abroad had a lasting impact in several ways. Beyond my own research, I built professional connections with professors, startups, and companies at UC Berkeley, creating opportunities for future collaboration. Networking is crucial in academia, and I am confident these contacts will remain valuable. I am still in touch with several PhD students and look forward to meeting them again in the future.
- Conclusion:
My time in California was definitely both professionally and personally rewarding. Engaging with students from diverse countries brought new perspectives to my work and daily life. Most importantly, the stay allowed me to focus and collaborate intensively on my research, which was crucial for successfully completing my PhD and ultimately deepened my passion for science and research.
