HubSpot Software Engineer(Internship) interview questions

I was contacted by a recruiter on LinkedIn, we had a short 15-minute phone interview. The questions were mostly about my experience and what I was looking to do in the future, nothing too challenging. Then I received the coding challenge. It was based on an API and you could choose the language. I finished it, however, was not what they were looking for and did not make it past that round. However, it was a good experience as I am new to applying to internships.
