Hopper Senior Software Engineer interview questions

Applied through a recruiter. First I had an half hour call with the hiring manager and it went well. He said Hopper has a long sequence of behavioral and technical interviews before they make an offer and such process proved successful. Then I had a technical interview with the hiring manager and a Senior Software Engineer. SSE was basically not supposed to ask any questions but watch it seems. During this, HM asked a few behavioral questions and proceeded to a shared technical challenge on Hackerrank. I thought I did well and I even solved what he called bonus points. TBH it is not easy to get syntax correct while coding on browser and it seems more suitable for Python programmers. Next day I received an email saying they found a slightly better fit for the position.
