Java Setup & Patterns, Apply-Now Sprint, Python from Zero, OOPs Begins

Install JDK 21+, configure IntelliJ IDEA / VS Code. Review variables, data types, operators, if-else, switch, loops. Write 4 small programs (hello world, calculator, temperature converter, leap year). TUF+ A2Z Step 1.1 Test-out: if you already code in Java, only install the toolchain and skip the toy programs.

Nested loop star and number patterns (right triangle, inverted triangle, pyramid). Time yourself. TUF+ A2Z Step 1.2 Test-out: if the diagnostic shows loop fluency, do 3 patterns as a check and move on.

Sit a 90-minute HackerRank-style OA (2 coding problems: one array/hashing Easy-Medium, one recursion/sorting Medium + 10 MCQs) under proctor rules, then a 60-minute post-mortem. Place out: any Phase 1 DSA task whose pattern you solve cleanly becomes a 30-minute review; spend the freed hours on the next unfinished A2Z step.

Big-O, Big-Theta, Big-Omega notation. Analyze 5 code snippets. TUF+ A2Z Step 1.3

Register on codeforces.com & leetcode.com. Solve 2 Codeforces Div.2 A problems to master submission mechanics.

Participate live in the weekend contest. Do not fear ranking. Upsolve 1 problem within 48h.

Install Python 3.12+, configure venv, create python-learning GitHub repo. Complete CS50P Weeks 0–2 (Functions, Variables, Conditionals, Loops) problem sets and push to GitHub. Test-out rule: if you already write Python for coursework, solve the Week 0–2 problem sets as a timed check and skip the lectures.

equals() and hashCode() contract (when to override, consequences of violating in HashMap), String pool and immutability, ArrayDeque vs Stack (why ArrayDeque is preferred), autoboxing/unboxing and primitive vs wrapper types.

Classes, Objects, Attributes, Methods, Encapsulation, Default & Parameterized Constructors, this() chaining in Java. TUF+ OOPs

Numbers: Basic + Advanced problem sets. Timed practice.

Visit TSEC TPC; record the CGPA threshold TPC confirms, backlog rules, tier (Dream/Super Dream) CTC thresholds and the first on-campus drive date T0 [VERIFY with TPC]. Initialize the Internship & Opportunity Tracker spreadsheet. Also confirm Sem 6 IAT1/IAT2, practical and ESE dates with the department and record your weekly lab, journal and mini-project load in the Tracker (Architecture §10).

Draft a 1-page recruiter-readable resume (quantified bullets, no photo/tables). Create a LinkedIn profile with education, technical skills and GitHub link; needed for the Apply-Now Sprint.

Lane 1 of the three-lane strategy (Architecture §9): within 72 h of Week 1 submit ≥ 5 applications to Summer-2027 / off-cycle programs still open. Check each official careers page and record status as [VERIFY]: Amazon, Microsoft, Uber, Atlassian, Adobe, Flipkart, Walmart, Intuit, Arcesium, D. E. Shaw, Razorpay, PhonePe, Goldman Sachs, JPMorgan, Morgan Stanley, GCC internships. Audit notes: Google SWE Intern 2027 India closed 28 Jun 2026; Goldman India 2027 Summer Analyst opened 1 Jul 2026 and is rolling [VERIFY]. Every OA invite is a free diagnostic: log each question in the Journal (a real OA in Week 1 exposes gaps ten weeks earlier than any mock). Filter first by graduation year (2028 batch only — many "2027" postings target the 2027 batch) and record each company’s re-application cooldown; skip any role where a failed OA would block your July 2027 attempt. Read the official careers page, not aggregators.
