How to Start a Career in Data Science in 2024?

Data science is one of the market’s most trending and popular career options in the technology field.

Despite how simple it may seem, Data science is a fast-growing and highly competitive field. Starting a career as a data scientist is not easy, therefore persistence is a must if you want to succeed.

To begin a job in data science as a beginner takes a lot of education, experience, and conceptual understanding.

In this guide, we have tried to help people who want to start their career in data science with almost no experience and knowledge.

What is Data Science?

Data science is the field of study that combines subject-matter knowledge, mathematics, statistics, artificial intelligence, and computer engineering to draw out useful insights from data.

The primary purpose of using data science is to collect data, process it, analyze it, and filter information from raw data.

Data science uses the most advanced hardware, programming languages, and algorithms to resolve data-related issues.

The future of artificial intelligence lies in it.

Simply expressed, data science is all about:

  • Presenting the right questions and analyzing the raw data
  • Using various advanced and effective algorithms to model the data
  • Visualizing the data to gain a deeper understanding
  • Understanding the data to find the final result and make better decisions

What Does a Data Science Engineer Do?

A data engineer is responsible for creating systems for gathering, validating, and preparing high-quality data. Data engineers collect and prepare the data, while data scientists use the data to support better business decisions.

The data engineer/ strategist’s job is to find and integrate new datasets that can be used to expand the functionality of the business and collaborate with the technical team to develop data products.

How To Start Your Data Science Career?

There are a few questions you should ask yourself before planning to pursue a career as a data scientist:

  • Do you love statistics, numbers, and graphs? Data science is entirely based on Maths and statistics. If you don’t like math, statistics, and numbers this is a red flag for you. If you don’t like working with numbers, you will find your job frustrating later in your career.
  • Before advancing to a justified data scientist position, are you willing to learn and work at the entry-level?
  • Are you able to program easily? Data scientists should be comfortable using a variety of programming languages, including R and Python.

You can move forward and begin learning the data science abilities once you have a positive answer to the questions above.

Let’s take a look at the steps to Becoming a Data Scientist

Step 1. Get an undergraduate degree in data science

To become a data scientist, you must first get an undergraduate degree in data science or a closely related field.

Most employers will want to see a bachelor’s degree to hire you as a data scientist. Getting a bachelor’s degree in a field like data science, statistics, or computer science is an excellent way to get started in this profession.

 A senior professional with a bachelor’s or master’s degree in IT/ computer engineering can pursue a career in data science by upgrading and retraining through online data science courses in the US.

Otherwise, if you’re looking for a data science bootcamp, post-graduation course or master’s in data science, GreatLearning’s online data science courses are a good place to start.

Step 2. Develop your skill set

Even though a Bachelor’s degree may give you a theoretical understanding of the topic, it is important to brush up on your programming, technical, and non-technical skills.

Below are some of the most necessary skills you require for this job.

  •  Programming languages like  Python, R, SQL, SAS, Java, Julia, JavaScript, Swift, Go, MATLAB, SAS
  • Technical skills like Machine Learning, Deep Learning, Processing large data sets, Data Visualization, Data Wrangling, Statistical analysis and computing, Mathematics, Programming, Statistics, and Big Data.
  • Non-technical skills like Strong Business Acumen, Strong Communication Skills, and Great Intuition on data that you are working on.

Check out our list of top data science books that will upgrade your skill sets.

Step 3. Get Certifications in Data Science

Getting Data Science Online Courses & Certifications is a great way to showcase your skills.  Instead of buying random data science courses on the internet, try to get free certification from trustworthy sources like Simplilearn, Naukri, and LinkedIn.

Here are some free certifications of data science tools to help you on your way:

These two are the most widely used tools among data scientist professionals and would be an excellent addition to begin your career journey.

Step 4. Find Internships and Entry-Level Jobs

The best way to enter the data science field is through an internship. Find a position that can help you improve your skills and help you to grow in your career.

After your internship, you can either stay with the same firm (if they are hiring) or hunt for entry-level opportunities for data scientists, data analysts, and data engineers.

You can earn experience and work your way up in your career as your knowledge and skills expand.

Step 5. Go for Higher education

While a bachelor’s degree may be sufficient to get you started in the ideal job and gain the necessary real-world work experience, a master’s degree in data science would help you to enhance your knowledge and empower you to grow in your field.

This work experience can make you more appealing to an employer for a high-level Position like a Data scientist. Here are some master’s degree options available:

  • Master of Computer Science in Data Science
  • Master of Data and Network Analysis
  • Master of Applied Data Science
  • Master of Science in Data Science

Important Data Science Skills To Master

There are two different types of skills required to master data science:

1. Technical Skills

Statistical analysis and computing, Machine Learning, Deep Learning, Processing large data sets, Data Visualization, Data Wrangling, Programming, and ig Data are some important technical skills that are required in master data science

2. Non-technical skills

Some of the most important Non-technical skills include Strong Business Acumen, Strong Communication Skills, and Great Data Intuition. You need to have the skill to make the right judgments and make quick decisions in this job.

Roles and Responsibilities of a data science engineer

Here’s a data science career tip from a data scientist:

Focus on Core Fundamentals

Edward Pinela III

Start by gaining a solid understanding of statistics, mathematics, and programming, and then apply these skills by working on projects that interest you to gain practical experience and build a portfolio that showcases your abilities.

Continuously learn and stay up-to-date with the latest advancements in the field. Network with other professionals and attend industry events to expand your knowledge and build connections in the field. 

As a data scientist, it’s crucial to have strong documentation skills in order to effectively communicate technical details, insights, and results to stakeholders. Documentation not only helps to ensure the reproducibility and transparency of your analysis but also facilitates collaboration and knowledge transfer within teams and projects.

I highly recommend investing time and effort into learning how to create effective data science documentation.

Is it hard to get a job as a Data Scientist?

A Data Science job is not as easy as it looks. It is not a field where you can get a job after taking a 15-day course. Data Science requires discipline, and determination while learning.

Data science is the field of people who are interested in numbers, Stats, and engineering.

Most people choose this career because of its perks and high demand, despite the fact that this field does not interest them in any way.

Ronald Van Loon, Big data and Analytics Course Advisor at Simplilearn

Businesses seek out talented individuals for Data scientist positions. Getting a data science course certificate does not make you a data scientist.

You need expertise, Knowledge, and years of experience to be a data scientist.”

Ronald Van Loon (Big data and Analytics Course Advisor at Simplilearn)

In an interview with Simplilearn, he talks about developments that will drive the need for more data scientists in the future and the current state of demand for data scientists.

Although, you can apply for entry-level data science jobs like data engineer and data analyst with an undergraduate degree and data science courses.
