IT job interview preparation and career tips

1Craft the Perfect Resume

Your resume is your first impression. Focus on impact, not length. Include projects with real-world applications and quantifiable results.

One page is ideal for freshers. Use action verbs and focus on achievements, not just responsibilities.

2DSA Topics That Matter

Master arrays, strings, linked lists, trees, and graphs. These topics appear in 80% of interviews. Practice 100+ questions minimum.

Use LeetCode or HackerRank. Start with easy problems and gradually increase difficulty.

3System Design Basics

Understand databases, caching, APIs, and scalability. Even for junior roles, basic system design knowledge is expected.

Focus on real-world examples like Instagram, Twitter, or YouTube at scale.

4Behavioral Interview Mastery

Use the STAR method: Situation, Task, Action, Result. Prepare 5-7 stories showcasing teamwork, problem-solving, and growth.

Practice out loud. Talking through your approach is as important as the technical solution.
