In order to ease your path to become a Data Scientist, we have listed some of the steps and key skills required to help you kickstart your career as a data scientist:

• Earning a degree or a certificate: This is crucial as the job market in Data Science is particularly complex. A major company would generally look for a Master degree if not a PhD from an applicant in Data Science. Moreover, a degree and certificate will add credibility to your CV.
• Understanding Unstructured Data: The fundamental work of a Data Scientist is to go through the volume of unstructured data and manipulate it to get optimum results. 
• Learning about Software and Frameworks: Learning how to categorize unstructured data should be accompanied with working on various software and popular frameworks. You also need to learn a programming language to go along with the framework. The most preferred language in Data Science is Python and R. 
  • R has a steep learning curve, which really does not make it an easy programming language to learn. But it is one of the most used Programming Languages. Nearly 43% of Data Scientists use R programming language to analyze their data.
  • Hadoop as a framework is useful for Data Scientists to handle excess amount of data. In case the volume of data goes over the given memory at hand, Hadoop is used. Spark is a similar framework used in such situations as well. Spark provides a few more advantages over Hadoop like faster computational work and prevention of data loss.
  • Apart from the software and framework, it is required from a Data Scientist that they are expert in knowledge databases, as well. As such, they need to be skilled in SQL queries.
• Understanding Machine and Deep Learning: After data has been prepared, it is important for you as a Data Scientist to be able to apply algorithms to ease out analysis. We can train our model using deep learning techniques and analyze the data. 
• Understanding Data visualization: Data visualization involves communicating the analyzed data to non-technical colleagues in the form of graphs and charts. This is critical as communicating the same to them will lead to a better team effort. The general tools that are used for such purposes are matplotlib and ggplot among others. 

At least 46% of Data Scientists hold a PhD degree, so, it is important that you continue with higher studies after Graduation to land a lucrative job. Below are some other benefits of getting a degree:

Helps with networking: Throughout your entire journey as a student and learner, you will get to meet and work with people who share the same kind of interests. This is going to help you immensely in the future when you will start working as a Data Scientist.

Being organized about learning: When you are pursuing a degree, you will have to keep up with the curriculum and follow a particular schedule. This is more beneficial and effective than studying without any planning.

• A weak STEM background (biochemistry/biology/economics or another similar degree/diploma): 2 points
• A non-STEM background: 5 points
• Less than 1 year of experience in Python: 3 points
• No experience of a job that requires regular coding: 3 points
• Independent learning is not your cup of tea: 4 points
• Cannot understand that this scorecard is a regression algorithm: 1 point

Having programming knowledge is one of the most critical aspects of being a Data Scientist. The main reasons are as follows:

Helps with working on Data Sets: As a Data Scientist, you will be required to work with huge amount of data. Programming knowledge will help you with such large data sets analysis.

Helps with Statistical application: A data scientist has to work with statistics. You need the ability to program to implement statistics. Without the knowledge of programming language, knowledge of statistics does not do much good. 

Helping out with Framework: Programming knowledge is also useful when trying to apply data science in the most effective way possible. Developing Frameworks becomes easier which, in turn, can be used to make sure that the right data is accessible.

If you want to get a job in the field of Data Science, you need to follow this path:

Starting out: Learn a programming language that you will be comfortable with. The most commonly used programming languages in Data Science are Python and R language.

Learning Mathematics: This is critical, since, as a Data Scientist, you will be working with raw data. Having a strong hold on Mathematics and Statistics will be helpful. You need to pay special attention to Descriptive statistics, Probability, Inferential Statistics to further your knowledge.

Understanding Libraries: This is important to perform tasks like data processing and for structured data plotting. Some of the most common libraries are SciPy, ggplot, Matplotlib and others.

Understanding Data visualization: Another important aspect of a Data Scientist job is to find patterns in unstructured data and to communicate the same to people who are from non-technical backgrounds. Therefore, data visualization becomes important. The libraries used for this task are ggplot2 and matplotlib. 

Understanding data pre-processing: The unstructured nature of data makes it important for data scientists to pre-process the data before making it ready for analysis. This is usually done through feature engineering and variable selection. 

Machine Learning and Deep Learning: Deep learning algorithms are used while dealing with a huge set of data. You need to have a tight grasp on topics like CNN, RNN, Neural networks, etc. 

Learning Natural Language processing: This is important to understand how the text form of data can be processed and classified.
