Data Science has become the hottest job in the IT industry and the demand for skilled data scientists is growing rapidly. Data Science involves a lot of research, development, and analysis of data. The benefit of data science is that you get to work on a number of projects at the same time, and you don’t have to be a master in one particular programming language.
If you want to get a job in the field of Data Science, you know that there’s a lot of competition. But just because you can count on one hand the number of people who have reached the level of expertise that employers are looking for doesn’t mean that you can’t be successful in this field. In fact, there are skills that will serve you well throughout your career, regardless of the industry in which you choose to work.
Regardless of your experience and skills, there are opportunities for a career in data science. As the demand for data analysts continues to grow, this field offers a very attractive career path for students and professionals.
Many people are not data scientists, but are interested in data and data science and want to know what skills they need to work in this particular field.
If you are one of them, you are in the right place. In this article, we will discuss the technical and non-technical skills needed to get a job as a data analyst.
Working closely with the business, you will create solutions that improve the company’s decision-making process by effectively identifying problems and leveraging data.
Your responsibilities will also include designing experiments, developing algorithms, and managing and extracting data to support other departments, customers, and the organization as a whole.
Before you submit your resume, check out some data analyst resume tips on LinkedIn and familiarize yourself with the following qualities and skills you’ll need for your future job:
1. Machine learning and deep learning
As the name suggests, machine learning is the process of creating intelligent machines that can think, evaluate situations and propose solutions.
By using machine learning to create accurate models, a company is more likely to identify profit opportunities and avoid risk. A working knowledge of many types of algorithms is essential.
Machine learning has reached the next level with deep learning. The design is inspired by brain cells. The simulation of the human brain is the goal of this system.
Here, a deep neural network with artificial neurons is constructed on a large scale. Many companies require knowledge of deep learning, so you should be familiar with this area.
Among machine learning experts, Python is the preferred language, and TensorFlow is the most popular Python library for developing deep learning models.
2. Commercial Acuity
To succeed as a data scientist, you need to understand your industry and the challenges your company faces.
When it comes to data science, you need to figure out what problems need to be solved for your business to thrive, and how to implement new strategies to help your business get the most out of its data.
To be effective, data analysts must understand how a business works. Even if you are not oriented towards business units, acquiring business skills will make you a better candidate than others.
The work of a data scientist requires a thorough knowledge of statistics. You should be familiar with statistical studies, distributions, maximum likelihood estimates, etc.
Machine learning is no exception, but one of the most important parts of your statistical knowledge will be determining when certain methods are possible or impossible.
Statistics are important for all types of businesses. Especially in data-driven businesses, stakeholders who make decisions and evaluate the results of experiments rely on your information.
4. Data visualisation
Data visualization in machine learning is one of the most interesting parts because it is more of an art form than a step on a complicated path.
A global approach is not appropriate here. Data visualization experts know what to do with visualizations to make them tell a compelling story.
There are several important types of methods and techniques for data analysis. First, familiarize yourself with charts such as the bar chart, the column chart, the circle chart, and then move on to more complex charts such as the waterfall chart, the thermometer chart, etc.
The analysis of research data can be supported by these diagrams. Univariate and bivariate analyses are much easier to understand when presented in the form of colored graphs.
If you’re wondering what tools to use at this point, don’t let your fears sway you. Different languages provide a number of libraries for creating complex graphics.
5. Big Data Intuition
This skill is perhaps the most important soft skill a data scientist can possess.
A data scientist with intuition and experience can discover things in large data sets that are not always obvious. A data scientist with the proper training should be able to become more proficient in this area.
These specific skills of a data scientist are not taught in schools, so they must be refined and acquired through experience and possibly self-study.
6. Programming skills
The increase in computing power is mainly responsible for the growth of machine learning. Communication with the machines is only possible via programming.
Is it important to be a better programmer? Well, technically, no. Nevertheless, you should be aware of this and be comfortable with it from time to time.
Choosing a programming language is the first step. Some examples are Python, R and Julia. Julia is a general purpose programming language with rapid prototyping capabilities and many data science libraries provided by Python. Julia is faster and better suited to data science.
7. Communication skills
When companies are looking for data analysts, they need people who can communicate their technical assumptions to employees in various departments, including sales and marketing.
As a data analyst, you need to connect with people from all walks of life, as this can lead to stronger relationships and better productivity.
The data scientist should also use data storytelling to communicate the results to the business. An accurate and consistent account of your story will enable all members of your team to understand the state of your business and everything that goes with it.
8. Arithmetic and Algebra
Understanding these concepts is especially important for companies launching their products and defining their data. Many companies find that small changes in algorithmic optimization or prediction can yield big results.
During an interview for a job in the field of data science, you may be asked to demonstrate your ability to derive machine learning results and statistics from other sources.
In many cases, an introduction to linear algebra or multivariate calculus is assumed so that the examiner can ask you questions in these areas.
If many implementations of Python or R are available out of the box, why would a data scientist want to learn them? The answer is that at some point, the data science team can create its own insights that can be critical to development.
Becoming a data analyst is a long road. It can be difficult to find the time to continually update and maintain your technical skills. It’s time to hone your Data Analytics and Data Science skills to finally find your dream job.
