Most asked Interview questions/topic in DSA for SDE-2?

I have started preparing for senior role and am planning to give myself 3-4 months for DSA basic to advance and leetcode simultaneously.

A little about me, i am a software engineer with 2.5 years of experience. I switched to product base last year before that, used to do DSA questions on leetcode until trees (no graph, dp, trie, backtracking). Once i got into new company, again lost my flow and now feel like everything is forgotten.

After a month of procrastinating, i have finally started with basics and journey is until i am hands on with patterns again and also cover the left out topics.

Any guidance would be appreciated!!
