Quick Answer

The first day counts: find out about dress code and schedule in advance, arrive 10-15 minutes early, remember names, listen more than you talk, ask questions and take notes. The first 90 days are your probation period – use them to learn and build relationships. HIRIO-AI accompanies you even after acceptance with onboarding tips.

You got the job – congratulations! Now the real adventure begins: the first day at the new company. This guide helps you score points from the start and set the course for a successful career.

Before the First Day: Preparation

The first impression doesn't start on the first day – but before. Use the time after acceptance wisely:

  • Clarify dress code: Ask HR or check the website/social media
  • Plan the commute: Drive the route once during rush hour
  • Research the team: Check LinkedIn to see who your direct colleagues are

FAQ: Common Questions About the First Day

What should I wear?

When in doubt: rather more formal than too casual. Observe what others wear on the first day and adapt.

Can I already ask questions on the first day?

Absolutely! Questions show interest. Just no critical or know-it-all questions.
