What the first round actually tests, a two-week preparation order, and the questions you should ask back.
The first developer interview is not testing how much you know. It is testing whether the team can work with you: can you explain your own code, can you say “I don't know” and still make progress, and do you understand the fundamentals your resume claims.
Every line is a question. Pick your strongest project and be able to explain the data model, one hard bug, and one decision you would change. This is the highest-return preparation there is, and almost nobody does it.
Arrays, strings, maps, sorting, and the basics of complexity in the language on your resume. Two problems a day, explained out loud, matters more than fifty solved silently.
For whatever you claim: how data flows through a request, how you would debug a slow query, what happens between a form submit and a stored row. Fresher interviews usually go deep on one thing rather than wide across many.
Say your thinking while you code; ask about constraints before solving; when stuck, state what you know and what you are unsure about. Interviewers routinely pass candidates who needed a hint and fail candidates who went silent.
What does the first month look like in this role? How does the team review code? What does “done” mean for a ticket here? Their answers tell you more about the job than the posting did.
