LinkedIn Sr Software Engineer interview questions

I got contacted by a recruiter from LinkedId through this same network. She offered to apply to a position to work at Sunnyvale, California. Got phone screening lasting 30 minutes, just to getting know each other. After confirming my interest in moving forward, I got scheduled one week later for a technical remote test. This second interview was remotely using a zoom link. I was contacted by a Senior Software Engineer from the team they were looking to recruit. We had a brief introduction and continue to do the test which I was presented an embedded IDE web page to solve the interview question in 1 hour and a half. Unfortunately, I didn't pass it due to a lack of training in algorithms and data structures. In fact, it was easier. The next step would be an on-site interview to do whiteboards and design system problems but I didn't continue with the process. The recruiter was always in touch with me and she gave me useful feedback, encouraging me to try after one year and prepare. This definitely was a nice experience although I didn't get an offer.
