How should I prepare for an internship interview?

Research the company, prepare 3-5 stories about your projects using the STAR method, practice aptitude questions, and prepare your "Tell me about yourself" answer. Internship interviews are shorter than full-time interviews but test attitude, learning ability, and basic domain knowledge.

What are the most common internship interview questions?

Common questions include: Tell me about yourself, Why do you want to intern here, What are your strengths/weaknesses, Tell me about a project you built, Where do you see yourself in 5 years, and technical questions specific to the role.

How do I crack aptitude tests for campus placements?

Practice regularly with previous year papers, focus on Quantitative Aptitude, Logical Reasoning, and Verbal Ability. Use our free aptitude test section on MyInternships.in for timed mock tests. Most companies use 45-60 minute aptitude rounds.

What should I wear for an internship interview?

Business casual is standard for most Indian companies. For IT and startup companies, smart casual (neat shirt/blouse, formal trousers) is acceptable. For finance, consulting, and banking roles, formal attire (shirt, trousers/saree) is recommended.

Expert Tips

Revise your core engineering subjects from semester notes — interviewers go back to first-principles.
Describe your final year project or internship in detail — have a 3-minute pitch ready.
Manufacturing companies value safety culture — mention safety practices proactively in technical discussions.
For PSU exams (GATE, BHEL, ONGC), practice previous year papers extensively — pattern is very repetitive.
Show enthusiasm for hands-on work and plant visits — that differentiates candidates in engineering interviews.
