Campus interviews are a pivotal moment for B.Tech students aspiring to secure a job before graduation. With intense competition, companies now seek more than just a degree—they look for technical competence, practical exposure, and strong communication skills.

This guide outlines everything you need to learn to shine in campus placements in 2025.

1. Understanding the Campus Recruitment Process

Most campus drives follow this structure:

• Aptitude Test: Quantitative, Logical Reasoning, Verbal Ability

• Technical Round: Coding or Domain-Specific Questions

• HR Interview: Personality, Cultural Fit, and Soft Skills

Tip: Know the difference in preparation needed for product-based companies (e.g., Google, Amazon) vs service-based companies (e.g., TCS, Infosys).
