A selfie with my Analytics team

For those who don’t know, Bloomberg is a global pioneer in financial technology. Bloomberg provides financial software tools and enterprise applications to its clients in the financial markets.

I worked with their Analytics & Sales team in New York. Bloomberg’s analytics and sales teams are essential to their business. Analytics representatives deliver timely and accurate financial information to clients, provide subject-specific training, develop expertise across asset classes, and deepen product knowledge to advance through the sales ranks. The sales team has one focus: to sell the main terminals and generate revenue for the company.

What did you do during your internship?

During my internship, I had the opportunity to gain hands-on experience working with Hedge Fund clients and sell-side ERM banks such as JP. Morgan, Bank of America, Morgan Stanley. I used my technical background to work one-on-one with C-Suite clients to help them read and interpret financial data and deepen their analysis using machine learning tools in Python and Apache Spark.

Based on the success of my data science internship, I have been offered a full-time position starting July 2023.

  1. Don’t worry if you don’t have any technical knowledge
    (Before enrolling in the MS-ADS program)
    Coming as an intern specializing in public policy and technology, I have often struggled with impostor syndrome. I was intimidated by my peers who majored in finance and economics. In fact, there was constant concern that others would be more favorable to Bloomberg’s team. Fortunately for me, that notion quickly dissipated.
    I truly found my calling while interning at Bloomberg, and I attribute it all to knowing the value of just being yourself and contributing. Although I do not specialize in finance, I shine as a practitioner with experience in different programming languages ​​and technical software applications.
  1. Use your new skills
    I had special opportunities because of who I was only A practitioner with previous experience in Python, SQL, Apache Spark, Hadoop, and R, these are the skills I learned in MS-ADS classes.
    For example, I got to work with Bloomberg’s Quants team!
    I’ve also had the opportunity to work one-on-one with prominent figures in the Hedge Fund community (such as Equity Analysts). In this context, I used Python packages (Pandas, Matlab, Numpy, etc.) to create predictive models and visualizations.
  1. Network
    If I’ve learned anything during my internship at Bloomberg, it’s that it’s not about networking what You can do it, that’s about it WHO you know
    Networking is important to your career, but to reap the benefits, you need to master the following skills: first, network with purpose. This means connecting with a specific person, understanding their role/title, and knowing what kind of conversation you’re trying to have.
    In general, think about what you want to get out of the relationship and that will guide you on your way. Second, give as much as you get. Networking isn’t just about what you can get from others, it’s about what you can get in return. I want you to know that you can be there for them just as their network is there for you.
    The right networking allowed me to get my name into rooms I’d never even been in, but it got me a full-time job offer, and it could happen to you, too.

    After our team presented their final sales project to over 200 Bloomberg employees, including Global Heads, Sales Managers, Team Leaders, and the Head of Bloomberg.

  1. Metrics matter
    As an intern, you must fully immerse yourself in the life of a full-time employee at the company. That was my experience at Bloomberg. The transition from a college mindset to a full-time employee mindset is physically and mentally draining at first, but you keep pushing forward despite the obstacles.
    Here’s my tip on why metrics are important: they help you organize your day. Know what you need to do each day by marking your day in your notebook and planning your day. Additionally, by recording your weekly metrics in an Excel spreadsheet, you can see where you are doing better and where you need to improve.
    As an intern at Bloomberg, we were expected to provide metrics for weekly client calls/emails, internal campaigns, and client visits. I was able to beat these weekly goals because I wrote everything down.
    It’s also useful to write down your metrics when it’s time to evaluate your interns. During the review process, I was able to easily list my accomplishments, weekly metrics, and how I exceeded my goals. Doing this finally gave me a reward. If you want to succeed as an intern and receive a full-time offer, make sure you keep track of all your hard work. This will allow your employer to know the value you can add to their organization and thus qualify you for a full-time role.
  1. Develop your soft skills
    Soft skills range from effective communication to presentation style and critical thinking. Working at a firm like Bloomberg requires teamwork, interpreting data, interacting with clients, and more.
    During my internship, I was forced to step out of my comfort zone. Many of us struggle with public speaking anxiety, but it’s a critical skill to be successful in this business. I used to give back-to-back presentations to my team and to client meetings, but guess what? However, I overcame my presentation anxiety and learned how to give great speeches and communicate effectively. Additionally, I learned how to tailor my speech to the audience. In the end, I became an expert on the topics I was promoting.
    These skills will come in handy wherever I go. The more you practice, the better your experience in production will be.
