Be a data-driven job seeker


The goal was to examine the current data science job market in California. Which city has the most job posts in CA and offers more opportunities? As a current Data Science Master’s student, I wanted to find out which jobs a master’s degree holder would be eligible to apply for and what skills are most in-demand. Based on my findings from the data that I have collected, I have conducted an Exploratory Data Analysis (EDA) to investigate California's market.
