    3. Aptitude Preparation

    Aptitude tests are the first filter—clear this, and you're in the game. Most companies use aptitude to shortlist from hundreds to tens of candidates.

    Aptitude Components

    Quantitative Aptitude (Most Important)

    • Arithmetic: Percentage, Profit/Loss, SI/CI, Ratio, Time-Speed-Distance, Time-Work
    • Algebra: Equations, Progressions (AP, GP)
    • Geometry: Areas, Volumes, Coordinate Geometry
    • Number System: HCF/LCM, Divisibility, Remainders
    • Permutation & Combination: Basic counting, Probability

    Logical Reasoning

    • Blood Relations, Seating Arrangements, Syllogisms
    • Series (Number, Letter, Figure)
    • Coding-Decoding, Direction Sense
    • Puzzles, Statements & Assumptions
    • Data Interpretation (Charts, Tables)

    Verbal Ability

    • Reading Comprehension (RC)
    • Grammar (Error Spotting, Sentence Correction)
    • Vocabulary (Synonyms, Antonyms, Analogies)
    • Para Jumbles, Cloze Test

    Aptitude Preparation Strategy

    1. Learn concepts and shortcuts for each topic
    2. Practice topic-wise for first few weeks
    3. Then practice mixed tests under timed conditions
    4. Focus on speed—most tests are time-constrained
    5. Identify weak areas and allocate more time

    Resources

    • Books: RS Aggarwal, Arun Sharma
    • Websites: IndiaBIX, PrepInsta, GeeksforGeeks
    • Apps: Testbook, AMCAT prep, Unacademy
    Time Target: Most aptitude tests give 45-60 seconds per question. Practice solving questions in under 1 minute. Speed comes from pattern recognition, not faster calculations.

    4. Coding & DSA Preparation

    For product companies, coding rounds are the most critical filter. Master DSA patterns and you'll crack most coding interviews.

    Essential DSA Topics

    TopicPriorityProblems to Solve
    Arrays & StringsVery High40-50
    LinkedListHigh15-20
    Stack & QueueHigh15-20
    Trees (Binary, BST)Very High30-40
    GraphsVery High25-35
    Dynamic ProgrammingVery High40-50
    Recursion/BacktrackingHigh20-25
    Binary SearchHigh15-20
    Heap/Priority QueueMedium10-15
    Tries, Segment TreesLow (for advanced)5-10

    DSA Preparation Strategy

    1. Understand, don't memorize: Focus on understanding patterns, not solutions
    2. Code everything: Don't just read—write and run code
    3. Time yourself: Practice solving under time constraints
    4. Review solutions: After solving, study optimal approaches
    5. Revise regularly: Return to solved problems weekly

    Resources

    • Platforms: LeetCode (primary), GeeksforGeeks, InterviewBit
    • Sheets: Striver's SDE Sheet, NeetCode 150, Love Babbar Sheet
    • Courses: Striver A2Z DSA, Abdul Bari (YouTube), Aditya Verma (DP)

    During the Coding Round

    • Read the problem completely before coding
    • Think of edge cases upfront
    • Start with brute force, then optimize if time permits
    • Write clean, readable code
    • Test with sample inputs before submitting
    • Don't spend more than 20-25 min on one problem
    Quality Over Quantity: 200 well-understood problems are better than 500 problems you just copied solutions for. Focus on understanding patterns and approaches.

    5. Technical Interviews

    Technical interviews assess your problem-solving ability, CS fundamentals, and communication skills. They typically involve 1-3 rounds.

    What to Expect

    • DSA Problem Solving: Solve 1-2 problems on whiteboard/shared screen
    • Project Discussion: Deep dive into your projects, tech choices, challenges
    • CS Fundamentals: OS, DBMS, OOPs, CN (varies by company)
    • System Design: For experienced roles (basic for freshers)

    CS Fundamentals to Cover

    Operating Systems

    • Process vs Thread, Context Switching
    • Process Synchronization (Mutex, Semaphore, Deadlock)
    • Memory Management (Paging, Segmentation, Virtual Memory)
    • CPU Scheduling Algorithms

    Database Management Systems

    • ACID Properties, Normalization
    • Indexing, Joins, Transactions
    • SQL queries (practice writing)
    • NoSQL basics (Mongo, Redis use cases)

    Object-Oriented Programming

    • Four pillars: Encapsulation, Abstraction, Inheritance, Polymorphism
    • Design patterns (Singleton, Factory, Observer)
    • SOLID principles

    Computer Networks

    • OSI/TCP-IP model layers
    • HTTP/HTTPS, TCP/UDP
    • DNS resolution, IP addressing
    • Sockets basics

    Interview Tips

    • Think aloud: Communicate your thought process
    • Ask clarifying questions: Don't assume—clarify constraints
    • Start simple: Brute force first, then optimize
    • Handle hints gracefully: Incorporate feedback smoothly
    • Be honest: Don't bluff if you don't know something
    • Know your resume: Everything listed should be explainable

    6. Group Discussions

    Group Discussions test communication, leadership, team skills, and the ability to present ideas coherently under pressure.

    GD Format

    • 8-12 participants, 15-20 minute discussion
    • Topic given, 2-3 minutes thinking time
    • No moderator—group self-manages
    • Panelists observe and evaluate

    Common Topic Categories

    • Current Affairs: Technology, economy, politics, social issues
    • Abstract: "Is the glass half empty or half full?"
    • Case Study: Analyze a business scenario
    • Controversial: Topics with no clear right answer

    What Evaluators Look For

    • Content: Quality of ideas, examples, logic
    • Communication: Clarity, fluency, confidence
    • Body Language: Eye contact, posture, gestures
    • Leadership: Initiative, steering discussion, building on others
    • Team Player: Listening, acknowledging others' points

    GD Do's

    • ✅ Enter early with a strong opening point
    • ✅ Support your points with examples and data
    • ✅ Build on others' points ("Adding to what Priya said...")
    • ✅ Summarize if discussion is scattered
    • ✅ Maintain positive body language throughout
    • ✅ Listen actively when not speaking

    GD Don'ts

    • ❌ Don't interrupt or shout over others
    • ❌ Don't stay silent for too long
    • ❌ Don't get aggressive in disagreements
    • ❌ Don't repeat the same point multiple times
    • ❌ Don't bring up unrelated tangents
    Practice Tip: Form GD groups with classmates. Practice 2-3 GDs daily in the final month. Record and review your performance to identify improvement areas.

    7. HR Interviews

    HR rounds assess cultural fit, attitude, communication, and long-term potential. Many candidates fail here after clearing all technical rounds—don't take it lightly.

    Common HR Questions & Approaches

    "Tell me about yourself"

    Structure: Present → Past → Future. Briefly cover current status, relevant background, and future aspirations. Keep it 60-90 seconds.

    "Why do you want to join our company?"

    Research the company. Mention specific products, culture, values, or recent news. Show genuine interest, not generic answers.

    "What are your strengths and weaknesses?"

    Strengths: Give examples that demonstrate the strength. Weaknesses: Be honest, but show what you're doing to improve.

    "Where do you see yourself in 5 years?"

    Show ambition but also commitment. Balance growth aspirations with realistic expectations. Avoid saying you want the CEO's job.

    Behavioral Questions (STAR Method)

    For questions like "Tell me about a time when...", use STAR:

    • Situation: Set the context
    • Task: What was your responsibility?
    • Action: What did you do specifically?
    • Result: What was the outcome? Quantify if possible.

    Questions to Ask the Interviewer

    Always have 2-3 thoughtful questions ready:

    • What does a typical day look like for this role?
    • How do you measure success for someone in this position?
    • What are the growth opportunities within the team?
    • Can you tell me about the team I'd be working with?
    Common Mistake: Being negative about previous experiences, colleges, or professors. Stay positive even when discussing challenges. Focus on learnings, not complaints.

    8. Resume & Profile Building

    Your resume is your first impression. It determines whether you get shortlisted and shapes interview conversations.

    Resume Structure

    1. Header: Name, Email, Phone, LinkedIn, GitHub
    2. Education: Degree, College, CGPA, Year
    3. Experience: Internships with impact metrics
    4. Projects: 2-3 significant projects with tech stack
    5. Skills: Languages, frameworks, tools
    6. Achievements: Competitions, certifications, publications

    Resume Tips

    • One page only: Unless you have 5+ years experience
    • Quantify impact: "Improved X by 30%" not "Worked on X"
    • Use action verbs: Designed, Implemented, Optimized, Led
    • Tailor for role: Highlight relevant skills for target companies
    • Proofread: No typos or grammatical errors
    • ATS-friendly: Simple formatting, standard fonts

    Project Presentation

    For each project, be prepared to discuss:

    • Problem it solves and motivation
    • Tech stack and why you chose it
    • Your specific contribution (especially for team projects)
    • Challenges faced and how you overcame them
    • Future improvements you would make

    Online Presence

    • LinkedIn: Updated, professional photo, connections
    • GitHub: Clean repos, good READMEs, regular activity
    • Portfolio: Optional but impressive for developers

    9. Company-Specific Preparation

    Different companies have different interview patterns. Research your target companies thoroughly.

    Product Companies (Google, Microsoft, Amazon)

    • Heavy DSA focus (LeetCode medium-hard level)
    • System Design for experienced roles
    • Behavioral questions (especially Amazon—Leadership Principles)
    • 2-4 technical interviews + 1 HR

    Finance (Goldman Sachs, Morgan Stanley)

    • Quantitative aptitude (tough puzzles)
    • DSA (medium level)
    • CS fundamentals (OS, DBMS)
    • Finance basics (optional but helpful)

    Consulting (McKinsey, BCG, Bain)

    • Case interviews (practice structured problem solving)
    • Behavioral and fit questions
    • Group exercises/GDs
    • Less technical, more analytical

    Service Companies (TCS, Infosys, Wipro)

    • Aptitude tests (quant, logical, verbal)
    • Basic coding (simpler problems)
    • Communication skills important
    • HR fit and attitude matter more

    Research Resources

    • GeeksforGeeks: Company-specific archives
    • LeetCode: Company tags for problems
    • Glassdoor: Interview experiences
    • College seniors: Direct insights

    10. Mastering Mock Interviews

    Knowledge isn't enough; delivery matters. Mock interviews bridge the gap between knowing the answer and explaining it clearly.

    How to Conduct Effective Mocks

    • Peer-to-Peer: Find a serious study partner. Alternate roles of interviewer and interviewee. Give honest, brutal feedback.
    • Record Yourself: Use your phone or Zoom to record answers. Playback to spot "ums", "ahs", and poor body language.
    • Simulate Pressure: Set a strict timer. Have the interviewer look stern or ask follow-up questions aggressively.
    • Platform Mocks: Use Pramp or InterviewBit for free peer mocks with strangers to simulate real interview anxiety.

    Checklist for Feedback

    • Did you clarify the question before solving?
    • Did you think out loud?
    • Was the code syntax correct on whiteboard/paper?
    • Did you handle edge cases?

    11. Mental Resilience & Handling Rejection

    Placement season is a marathon, not a sprint. Rejection is guaranteed part of the process. How you handle it determines your success.

    Coping Strategies

    • The "Next One" Mentality: Give yourself 1 hour to grieve a rejection, then focus entirely on the next company.
    • Don't Compare: Your friend getting placed Day 1 doesn't mean you are failing. Everyone has a different timeline.
    • Health First: Sleep and nutrition directly affect cognitive performance. Pulling all-nighters before interviews usually backfires.
    Success is Non-Linear: Many students fail 10 interviews and crack the 11th one with the highest package. Consistency beats brilliance.

    12. Handling Offers & Negotiation

    The final stage! Dealing with job offers correctly is as important as getting them.

    Evaluating an Offer

    • CTC vs In-Hand: Don't just look at the big number. Check the base salary, joining bonus, and stocks (ESOPs/RSUs).
    • Role & Growth: A lower salary in a high-growth role (like SDE) is often better than a high salary in a support role.
    • Bond/Service Agreement: Read the fine print. Avoid heavy bonds (2+ years) if possible.

    Negotiation Tips for Freshers

    • Multiple Offers: Use a competing offer as leverage. "I have an offer of X from Company B, can you match it?"
    • Be Professional: Never be arrogant. Express gratitude while asking for better terms.
    • Standard Slabs: Note that many mass recruiters have standard slabs that cannot be negotiated.

    13. Frequently Asked Questions

    When should I start preparing for placements?

    Ideally 3-6 months before placement season. If targeting tier-1 product companies, 6 months is better. For service companies, 2-3 months is sufficient if fundamentals are strong.

    What CGPA do companies require?

    Most companies require 6.0-6.5 minimum. Top product companies sometimes have 7.0-7.5 criteria. However, skills matter more than CGPA once you clear the cutoff.

    How many DSA problems should I solve?

    Quality over quantity. 200-300 well-understood problems covering major patterns are better than 500+ problems solved without understanding. Focus on patterns, not just answers.

    What if I don't have projects?

    Start building! Even 2-3 months before placements, you can create meaningful projects. Focus on one solid project rather than many basic ones. Clone popular apps with your own features.

    Should I join coaching classes?

    Not necessary. Free resources (YouTube, LeetCode, GeeksforGeeks) are sufficient. Coaching helps with structure and accountability. Consider paid courses only if you struggle with self-study.

    What if I fail in placements?

    Off-campus placements and direct applications are viable options. Many successful engineers got their first job off-campus. Keep practicing, networking, and applying. Persistence pays off.

    Your Placement Journey Starts Now

    Campus placements can feel overwhelming, but with systematic preparation, they become manageable. Thousands of students crack top companies every year—with the right strategy, you can too.

    Remember: preparation is 80% of the battle. The remaining 20% is confidence and execution on the day. Build both through consistent practice and mock sessions.

    Start today. Pick one topic, solve one problem, practice one question. Consistency over intensity wins in the long run.

    Prepare well, stay confident, and land your dream job! 🎯💼🚀
