LinkedIn Phone Interview Tips - Staff SW

Phone Interview is a few weeks away. Worked on most of the LinkedIn tagged questions at LC (mostly medium and some hard too) so far. I believe the format would be 2 questions. And is it 1 Medium and 1 Hard? Any preparation expected outside LC? like Geekforgeeks or any? Has anyone given Linkedin PI lately and willing to share any other tips?
