Data science seems to be one of the hottest areas for innovation to disrupt various business domains these days, and while data-driven approaches are finding their way into each of those domains, companies are already fighting for Big Data talent in order to make better Business Intelligence (BI) based decisions.

Companies' increased focus on acquiring data analytics specialists is in line with the creation of a whole new set of Big Data roles and responsibilities. I've taken a look at the pool of data job postings to see what roles are most sought after by big name companies and compare their average cost in the United States and Ukraine, Eastern Europe's leading hub for data science outsourcing.
