HubSpot Senior Software Engineer 1 interview questions

A recruiter reached out to me via LinkedIn, and we spoke on December 9th. The recruiter was very informative and pleasant throughout our conversation. A few days later, I received a personalized three-hour coding assessment, which involved fetching data from an API, performing some processing, and posting it back to the API. Due to my schedule, I took the assessment a few weeks later. Unfortunately, I was unable to successfully complete the challenge, and I received a rejection email from the recruiter within 48 hours of taking of the test. I asked for feedback, but none was provided.
