Hello Data people.
Today, I’m very happy because I have the privilege to write about one of my favorite businesses of all time: VISA.
But, I’m even more excited because thanks to an incredible member of my network of contacts, I have access to the actual team hiring for the role I’m writing about today: Data Scientist at VISA.
For all that: a massive shout-out to Celinda Farías Appleby, who is a Director of Global Talent Attraction at VISA, a proud Latina, and a big advocate of developing talent.
Celinda was a key player in the work with this article because she was the one who asked several Data Scientists inside the company to answer some of my questions to put here.
So, thank you again Celinda from the bottom of my heart.
Let’s talk about some interesting facts about VISA
I don’t want to dig deeper into VISA, because there are so many resources out there to do this.
I will share here some of my favorite ones:
- VISA: The Original Protocol Business with Patrick O’Shaughnessy and Alex Rampell, in the Business Breakdowns podcast (highly recommended)
- How VISA makes money, Investopedia
- Visa Inc. Reports Fiscal Third Quarter 2022 Results (highly recommended as well)
And of course, we can’t talk about VISA and let this out:
As you can see, VISA is a big conglomerate, but they are trying to keep the pace of fintech these days, and they are looking for brilliant people to build the fintech infrastructure of the future:
Let’s talk about some interesting facts about the VISA Consulting and Analytics team

Some Q&A from the team
As I shared before, Celinda and the team at VISA shared some incredible insights about the dynamics of the team.
I will share their answers to some of the questions I made them.
What is it like to be a Data Analytics inside the Visa Consulting and Analytics team at VISA?
30% Communication: Before we start doing the project, we need to communicate with the client and consultant and know the goal of this project. Along with the project going, we need to explain the analysis results to the consultant, and they will build corresponding strategies based on the data.
30% Coding: Using different tech stacks (SQL, Python, Spark) to pull the data you need, performing statistical analysis, or building machine learning models to solve the problem.
30% Analytics and Visualization: Analysing the benchmarking result and model result, and creating a visualization plot to make the result more readable is another major part of our daily work.
10% Self-development and Group Study: Apart from the project, we also have multiple committees including the Social Committee, Coding Committee, and a variety of study groups, we can join based on our interests. And we could also participate in conferences or take online classes by using our training budget!
What is the favorite thing you love to be part of this team?
We can be exposed to different kinds of projects. It’s a great opportunity for people who want to try out different things and you can always learn something new from different projects. For example, I did a tableau dashboard project, a modeling project, and a benchmarking project last year, and my tech stack got extended from those projects!
What drives you every single day to work at VISA?
We all know that data foundation is critical as the basis for all the analysis. VisaNet transaction-level data can provide integrated and timely data for our client and our data scientist can perform various reporting and analytics based on that.
Can you share some details about the data tech stack at VISA?
The tech stack depends on what kind of project you are working on.
Spark SQL in Python is the most popular choice for the ETL tool.
Business intelligence and visualization tool are also an important part of our daily work, Tableau and Power BI are always the first choice.
Why is this role needed now, and what are you looking for in potential candidates?
Apart from the basic DS skill we listed in the job description, there are three more attributes we are looking for.
Passion: Passion is always the most important attribute when we look for a potential candidate. We will spend 1/3 of one day at work and we want you to enjoy this job!
Creative: Visa has the data foundation for all the analysis, but we also need creative data scientists to think out of the box and create new solutions for our clients.
Communication: Data Scientists in VCA need to work with the consultant to help the client solve their problems, the ability to communicate effectively with others and get along with different types of personalities will be a desirable quality in the job.
Some amazing insights here. Great communication skills + passion could help you to get this incredible role at VISA.
Let’s talk about the position
You can find the position here. Let’s dissect it piece by piece

It’s time for the ideas now to stand out in your job application here.
Let’s discuss two ideas on how to approach this job application (THE REAL MEAT)
Idea # 1: Participate in a Kaggle competition and share your notebook with the world (Bonus points if it’s related to payments)
It’s very simple: from my perspective, this is the best definition of “Building in public“ for a Data Scientist.
Being active at Kaggle could bring you a lot of visibility, and if your work is good; it will be recognized by the incredible group of experts inside the platform.
Idea # 2: Reach out to the team, especially Celinda and Sophie
They will be more than excited to answer your questions about it.
BTW, take notes from this post from Celinda:
