Difficulty: Focus on medium problems. Occasional hards. Staff coding rarely requires LeetCode hard tricks.
Volume: - problems total. Quality over quantity. Understanding patterns matters more than problem count.
Target performance: -% completion rate on mediums. You should solve them reliably, not struggle.
Time allocation: If you're already strong at coding, -% of prep time. If rusty, front-load it in weeks -, then maintain.
Don't let coding consume your prep. It's a bar check.
