Question 1
They did not ask any questions. The first interview was one of their automated technical tests.
great process overall, uses their own platform to dogfood, besides that they are remote forward company and are engineer focused. i believe the interview was thoughtfully planned out. There are areas of improvement everywhere but this place did it well
I applied through a recruiter. I interviewed at HackerRank (Irvine, CA) in Sep 2025
Interview
Somewhat fine, but had a problem with last minute rescheduling. Interview was rescheduled twice right before the original time and I was not consulted about the new time. Then, halfway through the full-loop, my interviews were cancelled without any word or reason.
The HR person said they wanted to move forward with other candidates, but not until the day after, wasting my time. All in all, personnel was good but the recruiter was very sloppy.
