Interview Preparation

“Cracking the Coding Interview”

The interview process for Software Engineering is standardized. You don’t need to be a genius; you just need to practice the specific patterns.

1. Data Structures & Algorithms (DSA)

This is 70% of the interview.

• Language: Choose C++ or Java (Python is okay, but C++/Java are preferred for core concepts).
• Platform:
  • LeetCode: The gold standard.
  • Blind 75: A curated list of the 75 most common interview questions. Solve these first.
• Topics: Arrays, Linked Lists, Trees, Graphs, Dynamic Programming.

2. Core CS Subjects (The Theory)

For Freshers, companies ask theoretical questions to check your basics.

• DBMS (Database): Normalization, SQL vs NoSQL, Indexing, ACID Properties.
• OS (Operating Systems): Processes vs Threads, Deadlocks, Memory Management.
• CN (Networks): HTTP vs HTTPS, OSI Model, TCP/IP Handshake.
• OOPs: Inheritance, Polymorphism, Encapsulation, Abstraction.

3. Behavioral (HR Round)

• “Tell me about yourself”: Have a 2-minute prepared pitch.
• “Why do you want to join us?”: Research the company.
• “Describe a challenge you faced”: Use the STAR method (Situation, Task, Action, Result).

Study Plan (3 Months)

• Month 1: Learn a language (C++/Java) + Basic DSA (Arrays/Strings).
• Month 2: Advanced DSA (Trees/Graphs) + Core Subjects (DBMS/OS).
• Month 3: LeetCode Grind (Blind 75) + Mock Interviews.
