Most interns spend their first week trying not to do anything wrong. They sit quietly in meetings, hesitate to ask questions, and wait to be told exactly what to do before they do anything. This is understandable but it is the wrong approach. The interns who get return offers are almost never the ones who stayed quiet and tried not to bother anyone.
The first week is your chance to establish how people perceive you for the rest of the summer. Recovering from a weak first impression is possible but it takes time you do not have in a twelve-week internship.
Understand the Environment Before You Try to Contribute
Before you do anything else, spend the first two or three days learning how the team works. How do they communicate? Is everything in Slack or do they do long email threads? How are tasks tracked? What does done mean for the team? Who do people go to when they are stuck?
You will not figure all of this out in two days but you will learn enough to avoid the obvious mistakes. The intern who sends a formal email to the entire team about a minor question when everyone uses Slack has already created an awkward impression that is hard to shake.
Ask More Questions Than Feels Comfortable
Most interns do not ask enough questions because they are afraid of looking stupid. This is a trap. Asking clear, specific questions signals engagement and curiosity. It also prevents you from spending four hours going in the wrong direction on something that a two-minute conversation would have clarified.
The questions that actually make you look bad are not the ones that show you do not know something. They are the ones that show you did not try anything before asking, or that you are asking the same thing repeatedly without absorbing the answer. Ask once, take notes, and reference those notes before you ask again.
Deliver Something Small in the First Week
If there is any way to ship something in your first week, even something small, do it. A bug fix. A documentation update. A minor feature addition. Something that you can point to and say I did that.
Early delivery signals competence and momentum. It gives your manager something concrete to mention when they talk about how your onboarding is going. It also gives you confidence that you are capable of contributing, which changes how you show up in your second week.
Build Relationships Outside Your Immediate Team
The interns who get return offers tend to be the ones who are well-liked across the organization, not just by their direct manager. In your first week, introduce yourself to people in adjacent teams. Go to any optional social events. Have lunch with people you have not met yet.
Engineering is collaborative. The relationships you build in the first week create the context for everything that comes after. Someone on a different team might be working on a problem you can help with. Your manager talks to other managers. The intern who is known and liked across the company has a different experience than the one who keeps their head down and talks only to their direct team.
The Bottom Line
Show up on time, ask good questions, deliver something small, and talk to people outside your immediate team. None of this is complicated. But most interns do not do all four things in the first week, and the ones who do are the ones who end the summer with return offers.
