A successful internship has three phases: preparation, execution, and follow-up. In this guide, you'll get concrete advice for each phase so you make the best possible impression.
Before: Preparation is key
Good preparation sets you up for success. Here's what you should do before starting:
- Research the company: Understand their products, services, culture, and recent news
- Clarify expectations: Know what tasks you'll be doing and who your supervisor is
- Set personal goals: What do you want to learn and achieve during the internship?
- Prepare questions: Show interest by having thoughtful questions ready
- Plan logistics: Know how to get there, what to wear, and when to arrive
During: Make a strong impression
The internship itself is your extended job interview. Every day matters.
