Uber phone screen/interview

Sky is the limit.. depends on job profile, also recruiter can help. Or search glassdoor

Focus on fundementals, be it algos, or design

SDE interview First round was one problem similar to leetcode medium level, expectations - you have to discuss solutions and make the code run. You can ask your recruiter tho

Medium lc ..most probably dp/graph

Assuming this is for software engineer role - Prioritize graphs, lists, stacks and queues. Dont worry much about dp. Practice writing code on online editors like hackerank, leetcode etc.
