Data mining specialists need a strong background in data science, as well as business administration. Relevant undergraduate degrees include computer science, data science, information systems, statistics, and business administration, or any related fields. If possible, you’ll want to get an entry-level job while still in college, especially in IT. Once out of college, look for positions as a data analyst. This will let you hone your technical skills further and develop an all-round understanding of the process of data extraction, transformation, and loading.
You may want to begin your career as a data mining specialist with a company that provides opportunities to contribute to a team working at the forefront of data science. Software corporations and computer manufacturers are example industries where you are likely to find this type of opportunity.
