From Classroom to Corporate: Student Placement Success Stories

Breaking into Banking AI: Tejaswi's Journey at DBS

For many students, the leap from academic theory to real-world application feels daunting. Tejaswi Pala, a final-year Data Science and Artificial Intelligence student at Nanyang Technological University (NTU), faced this challenge head-on through her Work Study Degree programme placement with DBS bank .

When Tejaswi first learned about the Work-Study Degree programme from her university's Career & Attachment Office in her second year, she recognized it as an exceptional opportunity to apply classroom knowledge to real-world work. While some students might view being attached to a single company as limiting, Tejaswi saw it as a strategic advantage. With a clear career goal of becoming a Data Scientist, she wanted to focus on one organization and immerse herself in developing strong, practical data science skills .

The Internship Experience:

At DBS, Tejaswi's responsibilities centered on building AI and machine learning models based on actual business needs. During her placement, she worked on a clustering model and a propensity-based AI/ML model, while also experimenting with other model types to strengthen her technical toolkit. Beyond the technical work, she led progress tracking for her projects and shared updates during weekly check-ins with her manager—developing the soft skills that would prove equally valuable in her career .

Overcoming Challenges:

Like many students entering industry, Tejaswi encountered significant hurdles. Her role required programming languages and tools she hadn't yet mastered, making the early stages particularly challenging. Additionally, coming from a non-business background, she struggled to understand DBS's business priorities, which made it difficult to determine which features to include in her projects .

Her approach to these challenges offers a blueprint for any student facing similar obstacles:

• Dedicated extra time practicing with new technologies

• Immersed herself in reading about DBS's key business areas

• Leveraged her team's expertise—colleagues willingly shared knowledge and patiently answered questions

The Transformation:

The results were remarkable. Tejaswi experienced significant growth both technically and personally. She strengthened her coding abilities and picked up new programming languages and tools that were previously unfamiliar. Perhaps most importantly, she gained invaluable insight into how data actually drives business decisions within a large organization .

Her advice to peers is direct and practical: "Start planning early and take a proactive approach towards your career goals. Attend career workshops and career fairs to understand employer expectations and explore career pathways. Have a clear goal to work towards, build your portfolio through internships or projects to gain practical experiences. Most importantly, believe in yourself. Many of us already have the abilities to succeed, but confidence is what helps us take the next step" .

From Interns to Hires: IE Masters Students Land Coveted Roles at BMC

The job market for tech careers has experienced significant turbulence in recent years, with global hiring freezes leaving many graduates struggling to find positions. However, for students at IE School of Science and Technology, the outlook has remained remarkably bright .

Career Changers and Upskilling Success Stories

Axel's Journey: From Marketing to Data Analytics at a Global Pharma Company

Not every data professional starts their career in tech. Axel's story is a powerful testament to the possibilities of mid-career upskilling and the value of investing in oneself .

Originally from France and now based in Tokyo, Axel studied marketing and business with an international focus, earning a Master's degree in International Marketing. He began his career in pharmaceutical market research—an industry he's now been part of for over a decade .

Recognizing the Skills Gap:

After moving to Japan, Axel joined one of the world's largest pharmaceutical companies. His role initially focused on classic market research, but over time it evolved to become increasingly analytics-driven.

"I understood the business very well," Axel explains, "but I didn't have the technical tools to go further." 

Technologies like SQL, Python, and analytics workflows were becoming essential, but they weren't yet part of his skill set. Axel wanted to understand how things actually worked, collaborate more effectively with data engineering teams, and deliver results faster.

The Limitations of Self-Learning:

Before joining a structured bootcamp, Axel attempted to learn on his own using no-code tools and achieved solid results. However, he encountered a common obstacle: learning always came second to urgent work tasks.

"I did make some progress," he says, "but only when I had time – and there was always something more urgent." 

What the bootcamp offered was structure and commitment—a defined timeframe where learning had to become the priority, even if it meant putting other things on hold for a few months.

Getting Company Funding:

Coming from a completely non-technical background, Axel joined the Le Wagon Data Analytics bootcamp with a clear goal: not to replace engineers, but to understand automation, data pipelines, and code well enough to use them wisely.

"I work with people who are experts in coding. If I understand what they do, I can work with them much more effectively," he reasoned .

Axel made his case to his manager with a simple argument: his role was evolving, and without new skills, he couldn't work efficiently within normal hours. Investing in training would help him deliver better results for himself and the company.

The company agreed and fully funded the bootcamp.

Life After Upskilling:

Right after completing the program, Axel went on paternity leave to welcome his newborn son. When he returned to work, he remained in the same role but started actively applying what he learned—Power BI for dashboards, SQL to read and understand queries, Python for analysis and automation, and no-code tools for rapid solutions .

The transformation in his confidence was dramatic:

"Before the Data Analytics bootcamp, I would read SQL queries and completely misunderstand them. Now, I can generally understand what a query does. If it gets complex, I might ask Copilot but at least I know what I'm looking at." 

That confidence extends to AI tools as well. Axel now knows when Copilot's output makes sense and when it doesn't.

In his day-to-day work, Axel sits at the intersection of marketing, data science, and data engineering. Sometimes he handles analysis or builds dashboards himself. Other times, he translates business needs for more technical teammates and helps ensure the right solution is built. He's become a business-savvy analytics bridge—a role that exists at the sweet spot of domain expertise and technical understanding .

From University to Global Tech Leadership

Jim Barista: From MBA Student to Data Governance Lead at Mark Anthony Group

Jim Barista's journey demonstrates that the path into data can be nonlinear and that skills from seemingly unrelated domains often prove surprisingly valuable .

Jim pursued an MBA in finance at Saint Xavier University, building on an economics background from the University of Illinois Urbana-Champaign. His interest in personal finance and investing drew him to the program, and he appreciated that SXU was close to home .

The Foundation:

Reflecting on his time at Saint Xavier, Jim emphasizes how the experience shaped his analytical thinking:

"The professors brought real-world experience into the classroom, which gave me practical tools I've used throughout my career. It also laid the groundwork for me to start writing investment research for Seeking Alpha, which has become a big passion of mine. The finance training helped me turn what was just a personal interest in investing into something I could actually do in a more serious way," Jim explains .

The Career Evolution:

Today, Jim serves as a data governance lead at Mark Anthony Group—the company behind White Claw and Mike's Hard Lemonade. In this role, he focuses on data quality standards, improving processes across the businesses, and ensuring that trusted data drives decisions .

Simultaneously, he writes investment research for Seeking Alpha, which he considers a meaningful way to stay connected to finance.

"My finance background helped, but so did the communication skills I developed in my data work. I spend a lot of time creating technical documentation and explaining complex ideas to different audiences—business teams, IT teams, you name it. That experience made the transition to publishing on Seeking Alpha feel natural. It's continued to sharpen my financial analysis and writing while expanding my network in the investing community," Jim shares .

Continuous Learning:

Embracing Saint Xavier's core value of "learning for life," Jim is now pursuing a Master of Science in Information Systems at Northwestern University to deepen his technical skills—all while working full-time and maintaining his writing practice .

His story illustrates a crucial lesson: data careers aren't just for those who started coding at age 12. They're accessible to professionals who bring domain expertise, communication skills, and a commitment to continuous growth.

Minjung Kang: From Korea University to Senior Data Analyst at TikTok

Minjung Kang's journey from South Korea to a senior data analyst role at TikTok illustrates the power of international education, strategic program selection, and the value of blending business acumen with technical skills .

The International Ambition:

Minjung had always been passionate about new experiences, which inspired her ambition to build a career beyond South Korea. As a child, she lived in China for three years and attended an international school. Later, during her undergraduate degree at Korea University, she completed an exchange semester in Germany and an internship in Indonesia .

"I've always been fascinated by how different backgrounds can shape unique perspectives and personalities. So, continuing my studies abroad—and eventually building a career overseas—was very important to me," she explains .

Finding the Right Program:

When Minjung graduated in 2019, big data and AI were becoming increasingly important. She wanted to build technical skills she could apply in business—and discovered that London Business School was launching a new Masters in Analytics and Management (MAM) programme that offered exactly that blend .

"The strong mix of strategic and technical learning allowed me to build on the knowledge I already had while gaining valuable analytics skills, ultimately giving me more career options," Minjung reflects .

The LondonLAB Experience:

One of the most transformative elements of her programme was the LondonLAB project—a hands-on consulting experience with real clients. Minjung was paired with a small restaurant chain in London whose main selling point was a weekly changing menu of seasonal soups .

Her group analyzed past sales data and discovered that weather changes significantly influenced sales patterns. They then built a menu forecasting tool that used the following week's weather data to generate menu options and predict their performance .

"Working with a small company was a huge advantage, as we engaged directly with the CEO and gained valuable feedback and insights from an owner's perspective. It was also great practice for the corporate world—and for the consulting roles I secured after graduating—because we had to apply essential management skills such as assigning tasks based on teammates' strengths, setting project timelines and organizing regular check-ins," Minjung explains .

The Value of Diverse Teams:

Minjung also emphasizes the importance of working in diverse study groups. For every course, she was grouped with the same teammates, building meaningful connections and a strong sense of teamwork. Some students had arts backgrounds, others had studied STEM—this diversity allowed them to draw on each other's strengths and approach challenges collaboratively .

Landing the Role at TikTok:

Today, Minjung applies what she learned every day as a Senior Data Analyst at TikTok. The Data Visualisation and Storytelling course remains particularly relevant—one of her key responsibilities involves maintaining and building dashboards and writing business reports .

"I always apply a crucial lesson from that course: visualising information in a way that tells the right story. When you have access to so much data, it's easy to get lost in the details and miss what's truly important for the business. But I learnt how essential it is to step back and frame the story based on the audience's needs," she shares .

The LBS Network Advantage:

Minjung also highlights the lasting value of the LBS network. She's now part of a global community she can always turn to for support. When researching companies, she often looks for LBS alumni because they're always open to connecting. When she moved from her first company to TikTok, a friend from LBS working there provided a referral .

"Having LBS on your CV makes a powerful statement. It demonstrates a strong work ethic and a desire for continuous growth. When I was entering a highly competitive job market, where candidates are primarily evaluated on their academic profiles, I was grateful to secure an offer before graduation. I have no doubt that the reputation of LBS played a crucial role in that," Minjung affirms .
