🏢 Company-Specific Preparation: Hitting the Bullseye¶

Not all companies interview the same way. A strategy for a service-based giant won't work for a high-growth startup.

📊 The "Big Three" Categories¶

1. Service-Based Giants (TCS, Infosys, Wipro, Accenture)¶

• Focus: Aptitude, English Communication, and Basic Technical Knowledge.
• DSA Level: Basic (Strings, Arrays, basic Linked Lists).
• Strategy: Master the previous year's papers (PYQs). Speed in aptitude is the primary filter.

2. Product-Based Companies (Amazon, Google, Microsoft, Adobe)¶

• Focus: Advanced DSA, System Design (for higher roles), and Core CS.
• DSA Level: High (DP, Graphs, Trees).
• Strategy: Intensive LeetCode practice. Master one language deeply. Be ready for multiple technical rounds.

3. High-Growth Startups (Zomato, Swiggy, Fintechs)¶

• Focus: Development Skills, Projects, and Culture Fit.
• DSA Level: Medium (Focused on practical problem-solving).
• Strategy: Have a stellar GitHub profile. Be ready to discuss your architecture choices and take-home assignments.

🔍 How to Research a Company¶

1. Glassdoor & AmbitionBox: Read interview experiences. What questions were asked last month?
2. LinkedIn: Find employees in the same role. Look at their backgrounds and tech stacks.
3. Company Engineering Blog: (For Top Tech) Read about how they solve their technical challenges. Mentioning this in an interview is a huge plus.
4. Recent News: Did they just raise funding? Launch a new product?

🛠️ Specialized Prep Sheets¶

• The "Blind 75": Essential DSA problems for Product roles.
• Striver’s SDE Sheet: Comprehensive path for SDE roles.
• Top 50 DBMS/OS Questions: For the theoretical rounds.

💡 The "Company-Fit" Cheat Sheet¶

[!IMPORTANT] The "Cultural Fit" matters: A startup might reject a genius coder if they seem too rigid or bureaucratic. A large bank might reject a hacker if they seem too reckless. Adapt your communication style.
