It's a professional courtesy to withhold the bulk of your questions until the interviewer asks if you have any. Interviewers typically ask toward the end of an interview or near the conclusion of each phase. Of course, it's okay to ask a few questions to clarify matters, steer topics and such, as the interview progresses. For example, a question such as, "What does the ideal candidate bring to this job?" would be appropriate early in the interview. But wait until it's "your turn" before you fire off a barrage. On the other hand, if the interview seems to be drawing to a close before the interviewer asks if you have questions and you have some, ask if it's okay to ask.
Avoid asking questions just to impress the interviewer, and asking frivolous questions just to have some to ask. Also avoid asking questions that might reveal more about you than the job. For example, the question "What happens if I fail to meet a project deadline?" has underlying implications, such as "I've often irresponsibly missed project deadlines."
It’s generally never a good idea to ask questions about salary or remuneration in general; holiday allowance, lunch breaks and so on. Upstream have arranged innumerable interviews and these are areas that we will negotiate effectively on your behalf. From an interviewer's point of view, asking such questions in the interview process will indicate that your priorities are in the wrong order which will likely reduce your chances of success considerably.
It's highly advisable to write down interview questions to ask beforehand, and then refer to them during interviews. It shows that you're organized and interested enough in the job to have researched the company and prepared in advance and will help you structure your interview which in turn will give you interview confidence.
