What Are the Job Opportunities in Big Data?



Data is an essential fabric of business intelligence. Data miners, almost every day, extract hundreds of data sets from 2.5 quintillion bytes of data. The IoT is responsible for its eruption in such a massive amount. Hats should be off to the data scientists and architects who hold it with expertise. Not only do they hold, but they also spot unique solutions through data analytics after mining.

It may sound that big data analytics jobs are a walkover. But, they are actually difficult. They are commendable jobs big data jobs where groundbreaking decisions depend upon. This is why the typical structure of the private as well as the government is meeting a turnaround time. Even, this sector invites candidates who, being data analysts or scientists, are capable of making discoveries in the government jobs. If you consider India, for example, there are hundreds of jobs in the government sector for freshers and grads for data researchers and scientists. To stimulate this effort, its prime minister has geared up subscribing data entry jobs through its official website.

If you talk about the salary package, it can raise your brows. Look at the salary packages of a data scientist in India and the USA. It’s indeed tempting to make career in this domain. 
      
A survey of McKinsey Global Institute states that the US is going to be short of nearly 190,000 professionals with analytical lens. You might have understood why you should be interested in data analytics as a career. Of course, there is a big scope for big data engineers, scientists and analysts.
