Before, during, and after an internship

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.

First week

  • Arrive on time every day
  • Listen more than you speak
  • Take notes and ask questions
  • Learn names and build relationships
  • Understand the company culture

Throughout the internship

  • Be proactive: Don't wait for tasks – ask how you can help
  • Stay positive: Even when tasks are boring, maintain a good attitude
  • Ask for feedback: Request regular check-ins with your supervisor
  • Document your work: Keep notes of what you learn and accomplish
  • Build relationships: Network with colleagues, not just your supervisor

After: The follow-up

What you do after the internship can be just as important as the internship itself.

  • Thank your supervisor: Send a personal thank-you message
  • Request a reference: Ask if you can use them as a reference
  • Stay connected: Connect on LinkedIn and stay in touch
  • Update your CV: Add the experience with concrete achievements
  • Express interest: If you want a job there, make it clear

Common mistakes to avoid

  • Being passive: Waiting for tasks instead of offering help
  • Complaining: About tasks, hours, or colleagues
  • Phone usage: Checking your phone too often during work
  • Poor attendance: Being late or calling in sick frequently
  • Not following up: Disappearing after the internship ends

Key takeaways

  • Prepare thoroughly before starting – research the company and set goals
  • During the internship, be proactive, positive, and build relationships
  • After the internship, follow up with thanks and stay connected
  • Document your achievements for your CV and future interviews
