HackerRank, a popular platform for practicing and hosting online coding interviews, today announced that it has acquired Mimir, a cloud-based service that provides tools for teaching computer science courses. Mimir, which is HackerRank’s first acquisition, is currently in use by a number of universities, including UCLA, Purdue, Oregon State and Michigan State, as well as by corporation like Google.

HackerRank says it will continue to support Mimir’s classroom product as a stand-alone product for the time being. By Q2 2020, the two companies expect to have an initial release of a combined product offering.
