Hopper Software Engineer interview questions

Applied online in February 2020. I was then sent an online coding assessment which I completed. Upon review, recruiter contacted me to set up an 1 hour chat discussing my past experience/projects, more about Hopper, and the role. Overall a good chat. After that, I set up a technical phone call interview with one of the senior engineers discussing my background, experience, and coding problem. That is as far as I went as I didn't do as well as I expected on the algo portion. Online coding problem is interesting but would be nice to get a feedback on it.

HR phone screening call which was then quickly followed by an invite to do an online Coding Challenge (2 hr hackerrank problem). Unfortunately my solution wasn't good enough to proceed. Felt like I could've used another 15 minutes. Oh well.
