From Marketing to Data: Una’s NUS MSBA Admission After 6 Years

Updated 2026/10/16

Can you still go abroad and switch tracks after six-plus years of work? Una did it. She studied International Business at National Chengchi University (NCCU), then spent five years as an ad optimizer at a media agency and a year and a half as a data consultant at a martech company. Eventually she left her comfort zone and applied for a Master of Science in Business Analytics (MSBA) in Singapore.

With solid work experience and clear goals, she moved step by step from an international business degree into data roles. She was then admitted to both NTU and NUS, put her six-year career on hold, and chose the National University of Singapore.

In this interview, Una explains how she turned her digital marketing experience into strong stories for her SOP and essays, how she got through exams and applications while working full-time, and how she weighed the practical side of applying later in her career. She also talks about how she approached choosing schools, how she managed her time, and the advice she would give future applicants. If you are thinking about switching fields, preparing while employed, or applying to an MSBA, her story should be reassuring.

National University of Singapore (NUS), MS in Business Analytics: Program Overview

The National University of Singapore (NUS) has long been one of Asia’s top universities. In the latest QS rankings, the university as a whole performs strongly, and its business school and school of computing both rank first in Asia. The MS in Business Analytics run jointly by those two schools (MSBA, official site) ranked first in Asia in the QS Business Master’s rankings every year from 2021 to 2025, and 11th worldwide in 2025.

The curriculum mixes theory and practice and aims to build skills across disciplines. Students complete core courses plus electives covering economic decision-making, data management, operations research, business analytics fundamentals and machine learning, and they can specialize in areas such as finance, healthcare, big data or risk analytics depending on their career plans. Another key feature is the Capstone Project: within one year, students complete a project with a partner company and a 3 to 6 month full-time internship, so they apply what they learn to real business problems.

NUS MSBA graduates do well in the job market. According to the official survey, over 94% of graduates are employed within six months of graduating, and business analytics graduates earn an average monthly salary of about SGD 6,000 (around NT$140,000). They work in finance, tech, consulting, retail and healthcare, in roles such as Business Analyst, Data Scientist, Product Manager and Risk Analyst. Those numbers suggest the program pays off in careers as well as training. Singapore is a finance and tech hub for Asia, and NUS has a wide alumni network and many corporate partners, which makes the MSBA a strong choice for international students who want to move across fields into well-paid industries.

Studying in the NUS MSBA

How has the NUS MSBA been so far: the program, life in Singapore, your classmates? Anything you didn’t expect?

The program is a lot more intense than I expected. After midterms I was buried in assignments and reports, and I started thinking I might as well go back to work, where at least I got paid 🤣

I’d heard Singapore was fast-paced and competitive, but only after arriving did I really feel how everything here is a competition! Still, the culture is close to Taiwan’s, so settling into daily life was painless. That was one of the main reasons I picked Singapore.

With 1.5 years as a data consultant behind you, how rigorous or difficult is the NUS MSBA coursework?

I never took a single data course in college. Everything I knew came from learning on the job in recent years. The first semester is mostly theory, like economics and operations research, which was a bit of a struggle for me after being out of school so long. But that’s exactly why I went to grad school: I wanted a stronger foundation so I’d understand the theory behind what I use in practice.

What is the mix of nationalities and work experience among NUS MSBA students? Are most of them already busy job hunting from the start?

These days it’s mostly Chinese and Indian students wherever you go 😆 Most of them are fresh grads, and they’re usually the ones pushing hardest on the job search. Classmates with work experience tend to be less anxious and focus more on coursework.

Why She Applied: Moving from Digital Marketing to Data Analytics

During your six years of work, what first made you think about moving from marketing to data analytics? What did you do or learn outside work to make the switch?

Honestly, I was bored XD And as the digital ad algorithms changed, I felt I had less and less control over my work, and I started wondering whether the role could be replaced. Bored and not feeling much sense of achievement, I took online courses in SQL and other things just for something new. Two years after finishing them, they actually helped me change jobs.

Across five years as an ad optimizer and 1.5 years as a data consultant, which experience most shaped your decision to do an MSBA abroad?

After switching, I realized how much I was missing 🥲 There are plenty of online courses now, but picking up a bit here and a bit there, I found it hard to see the whole picture.

In my last job I had to discuss building and using models with AI engineers, and I was constantly asking myself, “Is this right?” That feeling really bothered me XD

How do you choose when you go abroad for an MSc later in your career? Why not the more common MBA route?

Don’t be afraid of being older! It’s actually your advantage! Right after college I thought about grad school too, but no matter how much I thought about it, I didn’t know what to study. It felt like I’d just be avoiding having to get a job…

After years of knocking around in the workplace, I figured out what I like and what I’m good at. So I settled on my field without much hesitation and never considered an MBA (I’m really not interested ><)

Essays and Positioning: Turning Marketing Experience into a Data Strength

When writing your SOP and essays, how did you connect your marketing background to an MSBA application naturally?

Just be yourself, haha! Ask yourself honestly why you want to study this (and spend all that money).

If you can’t come up with a complete story even for yourself, I’d suggest thinking it over some more (just kidding… sort of)

But I believe a true story is the most convincing one!

What content or highlights do you think you have to emphasize, such as project experience, data skills or cross-team collaboration?

Data analysis is a must. I don’t think MSBA programs care that much about hard coding skills. They care about how you’ve used data to find a problem and solve it!

When preparing your CV, how did you find where your past work fit your application, and how did you turn that into strong bullet points?

My CV followed the same “be yourself” approach XD

The projects that made me want to do an MSBA (like the AI prediction model I mentioned), milestones I’m proud of (a client praising an analysis as really useful), and so on. Finding a good fit to put on the CV isn’t actually hard!

Without a programming background, how did you show you could learn across fields and keep up with the MSBA coursework?

Like I said, the MSBA’s coding bar isn’t high, but you still need to show you want to learn (even better if you’re already learning)! I used SQL a lot at work, and after finishing all my exams I started a Python course. I made a point of mentioning both in my CV and in interviews.

Also, NUS puts more weight on math than NTU does. If you’re still in college, please take statistics, calculus and linear algebra. I’d been out of school for years, and the very first interview question was whether I’d taken calculus, haha.

Timeline and School Choice: Balancing Applications with a Full-Time Job

How did you plan your timeline and split your energy between a full-time job and applications? How did you schedule both the GMAT and IELTS?

Step one: find a job where you can leave on time (?) But honestly, sheer willpower is what got me through the most painful part, the GMAT QQ

Plan what you’ll review each week, and study at least a little every day! If you work full-time, use public holidays to catch up on anything you’ve fallen behind on (and invite friends to lunch near the library so your social life doesn’t vanish; mental health matters too!).

Here’s my schedule. I set goals by quarter, and the timing worked out just right!

• April: Started GMAT classes after the Tomb-Sweeping Day long weekend
• July: Took the GMAT early in the month, rested for two weeks, then started IELTS prep
• October: Took IELTS mid-month, then, completely drained, worked on my application essays at a snail’s pace and still made the late-January deadline 🤣

Did you consider other countries or programs? With a stable career of six-plus years, how did you weigh career growth, tuition and opportunity cost?

I looked at schools pretty much all over the world XD

Europe, the US, Australia, Southeast Asia, even the Middle East. Brochures are free to download, so it doesn’t hurt to learn more!

One factor for me was how likely I’d be to find work locally after graduating. By elimination I ended up with Data Science and Marketing Analytics in the Netherlands and Business Analytics in Singapore. After talking to alumni, I found I didn’t like how the Dutch program was taught, so I went with Singapore without second thoughts.

Beyond the curriculum, what else mattered to you when choosing a school (for example alumni network, location, culture)?

The weather! When I started picking countries, I crossed off the UK right away. I just can’t handle dark, damp, cold winters 🥲

And given my plans after graduation, I cared less about the novelty of a short stint abroad and more about whether I could adapt to, fit into and even enjoy the local life and culture.

Comparing the NTU and NUS MSBA programs, which difference mattered most to you? Why did you end up choosing NUS?

Honestly, ranking was a big one. If I’m spending that much money and time, of course I want to go to the best in Asia XD

I’m not telling everyone to look only at rankings. You should just be clear about what your own priorities are when choosing a school!

Where NUS spends the first semester on theory, NTU focuses more on coding. In some ways that’s more practical and appealed to me, but I can build coding skills on my own. I can’t do that with a QS ranking 🤣

Also, NTU’s students are younger on average, mostly fresh grads, and I wanted to spend time with peers who had work experience!

The Journey: Challenges and Rewards of Applying Later

From international business at NCCU to digital marketing, data consulting and then studying abroad, which moments made you rethink your career direction?

Probably every evening after work when I realized I was just going through the motions (lol). I’m not someone with a big career plan. My first few years of work were a lot of stumbling around, figuring out what I did and didn’t like.

Luckily I’m a doer XD When I found something interesting at work, I’d dive in and dig into it. When the future felt pitch black, I read up on career planning and psychology. I really believe in Steve Jobs’s connecting the dots: one day you’ll find that what you tried during those lost moments links up into the story of your life (and your SOP)!

What doubts did you hear most often about applying later, and what worries did you have yourself? How did you deal with them?

What’s wrong with Taiwan? Will you earn back the tuition? Can you find a job there? You don’t need to deal with other people’s doubts. Just tune them out and pretend you didn’t hear 🤪 I didn’t have many worries myself. Over a 40-year career, 15 months of time and money is a tiny cost. How could it not pay off! And with no family obligations yet, I actually think this is the best time to go abroad.

For exam prep or your essays, did you use any resources (online courses, forums, consultants) to speed things up?

As someone working full-time, my attitude was that time is money, so I paid professionals to handle things 🙂

So I signed up for every prep class I could, and I had Jason help me with my essays. I was really happy with the result, haha.

I also joined OfferLand’s Mantou mentorship program, where I could ask a mentor questions about the application process. That helped a lot too.

Advice for Future Applicants

What would you tell people who are preparing applications while working, or who have years of experience and want to change fields?

There will always be plenty of noise around you saying you can’t do it and asking why you’d leave your comfort zone. I’ve always met that with an IDGAF attitude 🙂

Better to try now and fail than to regret never trying!

Even if things don’t turn out as you hoped, it becomes a good life story that can win over an interviewer when you write your SOP or interview later!

If you could do it again, what would you start preparing earlier? What are the two things most worth spending time on in the application process?

I think I timed my applications really well, haha. If I could redo one thing, I’d apply for scholarships earlier! Tuition is really expensive 🤪

• Getting to know yourself: Doing this at the application stage might sound too late (huh?), but I didn’t run into much trouble with my essays, and I think the main reason is that I knew clearly why I was applying and what I wanted from a master’s. Rather than scrambling headfirst into applications while daydreaming about life abroad, spend some time with yourself first. I think that change in mindset is part of applying later in life XD
• Talk to people at different stages: classmates who have studied abroad, friends applying to master’s or MBA programs, current students and alumni. You’ll get more insights, be mentally ready for whatever hole you’re about to step into (?), and make the decision that fits you best!
