Oracle Data Science Interview

Oracle did US$40 billion total GAAP revenue in FY 2018.

Larry Ellison co-founded Oracle Corporation in 1977 with Bob Miner and Ed Oates. Oracle is a household name in Databases since 1980’s. There are 5 million registered members in the Oracle Developer Community. In every vertical, Oracle has the top companies in the domain as their customers. More than 6.3 million students are supported annually in 128 countries by Oracle. Oracle acquired DataScience.com, whose platform centralizes data science tools, projects and infrastructure in a fully-governed workspace to jump start their data science practice. A company that has been building databases and investing heavily in Data Science is one of the most underrated places for Data Scientist to work at. It is a great way to start your Data Science career.
