Greedy, Sliding Window II, Spring Boot Begins, OA Diagnostic #2, LP Mapping

Assign Cookies, Fractional Knapsack, Lemonade Change, Find minimum number of coins (greedy for standard denominations). TUF+ A2Z Step 12.1

Valid Parenthesis String, Jump Game I & II, Minimum Platforms, Non-overlapping Intervals. TUF+ A2Z Step 12.2

Sit 2 unseen Greedy problems you have never attempted (pick from the LeetCode topic tag, NeetCode “similar questions” or a company list; never a problem named in any learning task), at least 72 h after the learning task — move the set to the first half of next week if needed. Format: 25 min per problem (35 min for a Hard), including 5 min for edge cases and a dry run; no hints, no AI. Pass bar: ≥ 1/2 solved inside the time box; on a miss, log the miss reason in the Journal and re-sit a fresh pair within 7 days.

Longest Repeating Character Replacement, Binary Subarrays with Sum, Count Number of Nice Subarrays. TUF+ A2Z Step 10.2

Sit 2 unseen Sliding Window problems you have never attempted (pick from the LeetCode topic tag, NeetCode “similar questions” or a company list; never a problem named in any learning task), at least 72 h after the learning task — move the set to the first half of next week if needed. Format: 25 min per problem (35 min for a Hard), including 5 min for edge cases and a dry run; no hints, no AI. Pass bar: ≥ 1/2 solved inside the time box; on a miss, log the miss reason in the Journal and re-sit a fresh pair within 7 days.

Solve 4 new problems from NeetCode 150 — Arrays & Hashing (Pass 2); time-box each at 25 min before any hint (2.5h includes editorial on misses), then log pattern and miss reason in the Journal. Never repeat a problem already in the ledger.

LeetCode Weekly Contest (+ Codeforces Div.2/3 when it fits) and mandatory upsolving within 48 h.

Create the PlacementPilot service (Spring Boot 4.x, Java 21) with clean layering (Controller → Service → Repository → DTO), constructor injection, profiles, and a first /applications REST resource. Capstone milestone 1: open a PR per feature, never push to main.

Map each of your 5 STAR stories to 2 Amazon Leadership Principles (e.g. Customer Obsession, Ownership, Deliver Results).

Calendar check against the Opportunity Calendar (Architecture §16); send ≥ 3 personalised outreach messages (alumni, seniors, recruiters) and log each in the Tracker; follow up open threads; ask for a referral 1–2 days after any OA invite; apply within 72 h of any new posting on the Target-40.

Take a 90-min OA diagnostic (2 coding problems) under proctor rules, then practise an Amazon-style Work Simulation and Work Style assessment (prioritisation scenarios, LP-aligned choices). Log every miss in the Journal. Why: Amazon OAs combine coding with work-style scoring.

25-minute timed mixed set (quant, logical reasoning, data interpretation) from IndiaBix / PrepInsta-style banks; log accuracy and seconds per question in the Tracker. Target: ≥ 70% accuracy by W28.
