the journey to hackerrank first began in july 2009, when computer science graduates vivek and hari worked at amazon and ibm (respectively) for about a year in bangalore. both were on interview panels, inundated with endless hours of resume reviews, phone screens, and onsite interviews. unqualified people were making it to the onsite, while some of their most capable, hardworking friends were passed on because of their gpa or lack of a prestigious degree.,the demand for hackerrank to identify the right developer skills has grown in tandem with the demand for software engineers. our first customers were primarily in technology (like airbnb, dropbox). by december 2016, our customer base not only grew to over 1,000 companies but also prevailed across several verticals, from auto to retail to finance. in fact, 5 out of 8 of the top banks in america rely on hackerrank to evaluate developer candidates.
