Key point
Proof beats claims
A recruiter cannot inspect your confidence. They can inspect a repo that runs, has clear solutions, and explains trade-offs.
Your repo is not a dump of code files. It is evidence that you can solve, communicate, and keep work organised.
What to ship
Name the repo something clear, like placement-dsa-practice. Keep it public unless your college has a rule against public code for a specific assignment.
Cover each pattern from this track: sorting/searching, two pointers/windows, recursion/backtracking, greedy/DP, and graph traversal. Add one short explanation per problem.
