Found Senior Software Engineer (Full-stack) interview questions

Intro call with recruiter to talk through experience and the role. The 1st interview is a 1 hour coding challenge in the language of your choice using CodeSignal. Its more of a real-world problem vs leetcode challenge. I was unfortunately rejected because my interviewers didn't get the "signals on the technical side" to move me forward. I reached out to see if there was any specific feedback, but unfortunately didn't get a response.
