5. Getting A Certified
Okay, I’ll say it: I’m a snob.
Obtaining a certification is an optional step, but it will enhance your opportunities of becoming a data scientist.
Consider it this way: a formal certification demonstrates the data science abilities you’ve acquired.
Microsoft, Cloudera, SAS, and more firms now provide data science credentials.
Here’s a rundown of some of the certifications you might earn:
- SAS Data Scientist Certification
- Certification as a Cloudera Certified Associate: Spark and Hadoop Developer
- Associate in Azure Data Science Certification from Microsoft
These credentials will also improve your chances of landing a good job soon.
6. Building A Portfolio
As you may be aware, putting up a portfolio represents the work you’ve done in the field of data science.
You will stand out as an excellent data scientist if you have a strong portfolio.
You may now diversify your portfolio with a variety of data science projects by establishing online profiles on sites such as:
- Tableau Public
This is the truth: by doing so, you’re really attracting the attention of a lot of employment recruiters.
So, in essence, you may construct a portfolio based on the employment function.
A position that requires data analysis, for example, will require you to have a portfolio that includes data analysis tasks.
7. Participating In Hackathons
Because doing is the best way to learn data science, there are a variety of online platforms, such as Kaggle, that allow active involvement in data science contests.
Furthermore, you will earn experiences that will be added to your CV and portfolio as a result of participating in these events.

The Skills Data Scientist Need
To begin with, the degree of mathematical expertise necessary to be a successful data scientist is a fiercely disputed topic, with some claiming that profound mathematical understanding is essential.
Others say that math expertise is less necessary than you may think because most statistical studies are performed using computer tools like Numpy.
So, for the most basic mathematical principles, go to DataScienceWeekly.
2. Programming Tools And Techniques
Data scientists benefit from programming skills in a number of ways.
For starters, having a programming language allows you to build scripts to automate one of data science’s most time-consuming activities.
In addition, you may use scripts to convert data from one format to another. You could, for example, convert data from a SQL query into a nicely organised CSV file and store it in a relational database.
3. Machine learning
You would evaluate the available data regarding previous fraudulent transactions and seek for trends as a Data Scientist working without machine learning.
For example, you may group the data and discover that transactions coming from a given geographic region, purchasing items from a specific category, and/or using a specific payment method are all extremely likely to be fraudulent.
Your Software Engineering team would next most likely create a mechanism that flags transactions like these for manual inspection.
However, by combining records of both fraudulent and non-fraudulent transactions as training data, you might apply machine learning to solve the same problem.
So, which one do you think you’d prefer? Learn more.
Is it better to do things the easy way with machine learning or the hard way without it?
The majority of data is kept in relational databases, as you may well know. Read this article; Generating Windows Server and SQL Server on Amazon EC2 estimates.
To deal with data, you must be able to query the database and retrieve the information you want. As a data scientist, this implies that knowing the foundations of SQL is critical. Lastly, these are the 15 Best SQL Courses and Certifications this year.
5. Statistical Methods
The most crucial ability for a data scientist is a solid knowledge of statistics.
To put it another way, you can have all the programming, math, and software abilities you want. It won’t help you if you don’t know how to correctly and fairly evaluate and report statistics.
For example, if you don’t know when to report the median or mean for a particular collection of numbers, you could end up with an output that is imbalanced by outliers.
So, now that you know how to become a data scientist and have the necessary abilities, let’s get started.
How do you land your first data scientist job?
Getting Your First Job As Data Scientist
According to my study, there are a few criteria that determine whether or not you will be considered for an entry-level data scientist position at a firm.
These variables are generally determined by your education and experience.
Many businesses consider experience to be the most important element, but because you’re reading about entering into the sector, I’ll presume you don’t have any.
Education isn’t a huge concern since you can always fill in the gaps by demonstrating the breadth of your abilities.
Keep in mind that some employers will refuse to hire someone without a tertiary education.
It’s worth noting that some employers may state in their job advertisements that only qualified individuals will be considered.
Following the different steps, such as:
- Acquiring the necessary knowledge
- Developing critical data science abilities
- Certificates of achievement
- Putting together a portfolio
- Taking part in a variety of competitions
Even if you don’t return to school, you will undoubtedly become a data scientist.
However, keep in mind that while some firms may advertise that they only hire individuals with degrees, they may become interested in you once they see your portfolio.
What exactly do I mean?
Okay, I mean that you should participate in hackathons to develop a strong portfolio.
This will help you develop your skills by allowing you to get experience by addressing a variety of data science challenges.
