What is data science exactly?
The easy way to explain the definition of data science is the application of math and computer programming to large amounts of data for predictive modeling to gain insight into which to make decisions. The focus here is on prediction to figure out something that hasn’t happened yet by looking at either trend data or having the ability to draw conclusions based on data.
What to consider at the beginning of your job search?
This is taking into account that you do not have a job after completing an internship, boot camp, or are a first-time job seeker after online self-study.
The hiring process can be brutal and the job application process can be long with many job postings having several applicants, so you need to stand out! Start with your most transferable skills
. Take inventory of what you already know and what you can leverage to build on.
Consider starting out as an entry-level data analyst at a consulting company or small organization which will usually have a more senior person to walk you through what is expected. You can also get your hands on several projects.
These jobs will get you in the door understanding the types of business insights, visualizations, analytical tools, and gets your hands on real projects you can leverage. This will allow you to build a solid skillset.
How Can I Get a Job in Data Science Without Prior Experience?
If you’re just starting your data science career, consider building a strong foundation in programming languages like Python, R, and SQL. Take advantage of online courses, tutorials, and projects to gain practical experience.

Learning a Programming Language
You can accomplish learning a programming language via a boot camp, an online course
, or a university setting.
The most common technical skills
The applications used to build and analyze data will require at least one or two of these. It is suggested that 2 or more are learned to be more versatile for roles that are open.
The interviewer will definitely ask several questions on how you have applied the language or give you a sample project or code exercise. A job application will not go into the level of coding details needed for the roles on job boards. It will be just used to weed out those that don’t have it.
A technical certification will prove to an employer that you have mastered a certain level of skill.
Explain What Interested You in the Role
This topic is extremely important and goes beyond the application process and just a job title. There are thousands who are just getting started in the field, but what makes you different
is going to stand out. If candidates are in it just because it’s the trend right now, that is not going to be beneficial to an employer and can hamper your interview process.
Decision-makers want to know the path you want to go down so they can determine where you fit in the organization. Is it machine learning or business intelligence? Is it predictive analytics you want to work with or just reporting and dashboards? Why are you passionate about it?
Work on Industry Projects/Build Portfolio
You may not have previous experience in an actual working environment, but there are ways to participate in projects
that a real data scientist would work on for practical experience. You can create your own project, enter competitions, and try to solve a problem or ask others to join or assist in creating your own learning path. This is an area where you can create your own relevant work experience or use it to work with potential employers who can convert that experience into a full-time job.
Working on side projects allows one to practice a skill set by coding, using mathematical skills, gaining domain knowledge, and having an online presence to show future employers through a portfolio profiling your best work.
Internships for Hands-On Experience
There are several ways to take advantage of an internship to show your value to a company as this is the ultimate gateway into a first job in data.
- Show your ability to utilize the tools they are using.
- Prove your ability to work with teams.
- Take advantage of having interaction with users of your project.
- Have regular talks with the hiring manager about the company and opportunities.
- Participate in or ask to shadow other workers that will align with your skill set.
- Start a track record of being dependable, curious, and a problem solver.
- Use it to learn about the day-to-day life of a data scientist
Create a List of Resources
This list of resources is key for any data scientist/machine learning engineer! It’s important to stay on top of the latest tools, methodologies, programming techniques, open-source languages, industry applications, industry insights, company write-ups for those that you are interested in, practice sites, and where you can go to get answers to questions.
Practice Communication and Interpersonal Skills
This is one key area employers are seeking, so if you have no job experience, there are ways you can gain communication and interpersonal skills.
In school, you worked on projects. If you trained outside of school this can also apply. You can self-evaluate how well you worked on team projects. Were you open with information? Did you help the team or let others do the majority of the work? Did you have leadership roles? Were you able to communicate your thoughts or ideas clearly? Were you an overall good team player and asset? You can also ask others where your weaknesses are
like an instructor, friend, or past co-worker.
Most of all, do you have passion for what you do? You can have the best skills but if you are a lackluster communicator, employers will not hire you. They look for those who want to learn, will add energy to their teams, and has the foundations to build upon.
Practice Data Modeling/Data Visualization
Every project or task in data science or machine learning will have some aspect of data modeling or data structuring and how to visualize the data. It’s important to be able to create a diagram that shows the relationships of stored data. It is also imperative to know how to present a graphic representation of data.
An interviewer will want to know that you have the ability to fully understand how to use data, show the data, get the most value out of it, and understand the connections of the structure.
Keep Up Your Mathematics and Statistics Skills
Most people don’t realize how much math and statistics play in data science/machine learning. The job boards don’t exactly scream mathematics, but it really is the core. Be sure you understand how to set up calculations for statistics, linear algebra, and calculus are all used to create algorithms to make predictions.
Frequently Asked Questions
