I applied online. I interviewed at HackerRank in Nov 2018
Interview
I applied for Software Engineering Winter Internship online in August. Had to email them expressing my interest in this role along with my resume attached. I got an email from HackerRank CTO Hari in November to schedule a telephonic technical interview. It was a 15-20 minute call. It was mostly about my projects.
Interview questions [3]
Question 1
What projects did you do other than those mentioned on your resume?
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.

I applied online. The process took 2 weeks. I interviewed at HackerRank (London, England) in Mar 2025
Interview
It was a interview on the Hacker Rank tool with some leetcode questions. Task wasn't too difficult to do. Interview was quite pleasant but I was slightly out of practice with Leet Code styled questions.
