Much has been written about ‘data is the new oil’ and ‘data science’ is one of the hottest emerging technology areas. Yet many of the aspirants who would like to get into this sector have many questions about the skill requirements, opportunities in the industry, job openings etc. In this article, we shall try to answer a few of the commonly asked questions and clear the ambiguity around the required skills and job roles.
● Almost 48% of analytics job openings are looking for a B.E./B.Tech graduate degree in the incumbent.
● 18% analytics job openings are looking for a postgraduate degree which is not MBA or M.Tech. This is a decrease from 26% a year ago.
● 8% of analytics jobs specifically require an MBA/PGDM degree.
● Just 13% of recruiters are looking specifically for graduates with no/ non-B. Tech degrees, up from 10% last year.
So here’s the question in everyone’s mind that then how do a fresher crack this industry?
I am interested in getting into data science as a career. What do I need to learn?
In the area of data science, broadly understanding of three areas are required:
1. Statistical /machine learning techniques & algorithms
2. Computing tools/languages
3. Business understanding
For the first two areas, skills need to be built through learning and training.
Business understanding is a function of exposure in the business and industry.
One can prepare by learning through examples, case studies, projects etc.
It will lead you to become an expert in data science. A data science expert is someone who can analyze huge amount of unstructured and structured data using advanced tools and machine learning algorithms to solve a real-world business problem.
Skills that are needed to get an entry-level job in this field.
1. Basic of statistics.
2. SQL
3. Knowledge of basic problem-solving.
4. Having a portfolio of projects.
In statistics, you need some basic knowledge like
1. Sampling.
2. P-value.
3. Hypothesis testing.
4. Experimental design.
Try to implement these concepts using python on small data sets, so that you can tell anyone that you are you have some practical knowledge. By doing this you will have an edge over other candidates who may just have a theoretical understanding of these concepts.
SQL will help you
1. To retrieve data from relational database
2. It stores data in your databases.
Many data analytics professional spend their time on writing SQL scripts.
You may get various job descriptions like data scientist, business analyst or big data this might be confusing for you you but do not get confused by different job titles by companies providing.
In reality, they go in the path of data analytics after B.Tech graduation in this
industry.
Python, R, MySQL or Excel are mandatory skills for this job. They are also looking for candidates who have a good knowledge of the algorithm and if you know the basic concepts in machine learning, then it would be like “icing on the cake”.
What are the job roles in data science?
Data Science Aspirants wonder about the kind of roles that are there in the industry for them. There are many roles and opportunities in organizations. It is pertinent to remember that data science or big data analytics can not be done with one person. It is a team that works on such projects and there are various functions
and roles that are needed. Let us decipher a few of such job roles and designations that you may come up with.
1. Data Scientist
A data scientist is like the master chef! He is expected to work with big sized and complex data to derive meaningful patterns/visualization for the business to benefit. He should know statistical and machine learning
algorithms, how to manage complex data sources as well as have a strong understanding of business. A tall order of requirements from a single person but a data scientist adds tremendous value to an organization’s data science and analytics journey.
2. Data Analyst
Data Analysts are curious people who have an analytical mind. They sift through tons of data to find out if there is a relationship by running statistical analyses or find out the root causes of an event happening, like, why the sales of a division in a geography is going down for a product line or developing a model for predicting fraudulent claims for a health insurance company.
3. Data Engineer
Data Engineers are the people who love to play with large scale databases and systems and typically come with a software engineering background. ln, a data science context they operationalize the analytics model developed by data scientist and data analyst team and, automate, deploy and make it run for clients/business.
4. Data Architect
In the context of a large organization with disparate sources of data, the role of data architect is very important. He creates the blueprint and map for data sources and data mart which is crucial for any data science or analytics
project.
5. Business Analyst
A business analyst, on the other hand, is more business savvy and looks at problems from the angle of business rather than the technicalities of data, algorithm, architecture, management etc. He is the one who will have a
better business/domain knowledge and uses data to support business processes. He may use different visualization and analytics tools/products for his findings and recommendations. Needless to say, all the above may start at entry-level and grow to senior levels and, also there could be other roles and nomenclatures that you
may come up with like data integrators, database administrators, data warehouse specialists, big data consultants etc. and there are always some overlaps in functions among these roles. NASSCOM has identified six areas of
specialization in the Big Data Analytics domain that is expected to drive growth in the sector: business analysts, solution architects, data integrators, data architects, data analysts and data scientists.
Where are the job opportunities?
