My first day as a software engineer is coming up in about a week, and I've never had an internship or professional job before. I'm nervous about being dropped into a large codebase and want to use the time beforehand wisely. So far, I'm planning to review the team's likely technology stack, Git, debugging, and the differences between development, staging, and production environments. Are there other skills or topics I should prioritize, or should I mainly wait and learn the company's processes on the job?

The best preparation may be setting realistic expectations and staying calm. Your first few days will probably involve access requests, setup, introductions, and learning how the team works. Interviews usually don’t cover the company’s repository structure, deployment process, or local development setup, so not knowing those things beforehand doesn’t mean you were unprepared. Take notes, stay curious, and focus on making steady progress rather than trying to prove yourself immediately.
Don’t try to master the entire tech stack in a week. You’ll learn most of the company-specific tools after you start. Being comfortable with basic Git, navigating unfamiliar code, reading logs, and debugging is plenty of preparation. The bigger skill is learning how to understand a large codebase: start with a small task, trace the relevant code path, read existing documentation and pull requests, and ask focused questions. Nobody reasonable expects a new hire to understand the whole system on day one.
Communication is probably the most valuable thing to practice. When you ask for help, explain what you’re trying to do, what you expected, what actually happened, and what you’ve already tried. Try to investigate independently first, but don’t stay stuck for days just because you’re afraid to ask. If someone doesn’t respond, follow up politely or ask another teammate, then thank them for their time.
That balance is what worries me most. I’ll make sure to try a few reasonable approaches first and include the details when I ask instead of just saying that something is broken.
