Prepare two or three questions before the interview, and expect to use one. The interview itself often answers some of them, and asking something already covered suggests you were not listening. Choose at the end, based on what you have heard.
Here are five that work for most fresher roles.
First: 'What does someone in this role usually spend the first three months doing?' This tells you whether there is training, whether you will be put on live work, and how organised the team is. The answer is often more honest than the job description.
Second: 'How do new people usually learn here: training, a mentor, or on the job?' Freshers learn most from the people around them. This question shows you are thinking about getting good at the job, not just getting it.
Third: 'What does good work look like in this team after the first year?' You learn how they judge people, and the interviewer gets to describe what they value, which most people enjoy.
Fourth: 'Is there anything in my answers today you would like me to explain further?' Use this one carefully, and only if the interview felt uncertain. It gives you a second chance on a weak answer. Some interviewers will take it up; some will not. Either is fine.
Fifth, for a technical role: 'What tools or languages would you suggest I get comfortable with before joining?' It is practical, it shows you plan to prepare, and the answer is genuinely useful if you get the job.
Avoid a few things in a first or second round. Questions about salary, leave and work-from-home are reasonable, but they belong to HR or the offer stage, unless the interviewer raises them. Questions you could answer from the company website ('What does your company do?') suggest you did not look. And questions that are really statements ('I am very hard-working, do you value that?') are noticed.
Listen to the answer. If something interests you, ask one follow-up: 'You mentioned the team supports a hospital client; is that where a fresher would start?' A good follow-up shows attention, and it often turns the last two minutes into a real conversation, which is what you want the interviewer to remember.
And if the interview really did answer everything, it is fine to say so: 'Thank you, I think you covered what I wanted to ask about the training. I am keen on the role.' That is better than inventing a question for the sake of it.
