"I don't know what they're going to ask me" is one of the most common interview fears there is, and also one of the least fixable through the method most people reach for first: trying to guess the questions in advance.
The fear is not really about the question list
You can find a hundred lists of common interview questions online. Reading them helps a little, but the fear rarely goes away, because the real source of it isn't a missing list, it's the fact that a real interview is a conversation, not a quiz with fixed questions. Interviewers follow up on what you just said. They ask about something specific on your resume. They react to the room.
No list covers a conversation that adapts to you personally. Which means the underlying fear, "what if something comes up I haven't prepared for," is actually correct. Something will. The question is what you have in place for that moment, not whether you can prevent it from happening.
What actually happens when you get caught off guard
An unexpected question doesn't usually catch you out because you lack the knowledge. It catches you out because you have to build an answer from nothing, in real time, while also managing how you're coming across. That combination is what produces the blank stare or the rambling non-answer, not a genuine gap in what you know.
Once you name the actual problem, structuring an answer under time pressure, it becomes a lot more solvable than "know everything in advance," which was never a realistic goal to begin with.
Two real fixes, and they are not the same thing
There are two legitimate ways to get better at this, and they solve different parts of the problem. The first is repetition: practicing enough spoken, unscripted answers that structuring one on the fly becomes a familiar skill instead of a rare, scary event. This is the long-term fix, and it's the one that actually makes you better at interviewing, not just better at surviving one interview.
The second is a safety net for the moment itself: something that can surface a relevant angle from your own real experience while you're mid-answer, so a blank moment has somewhere to go instead of dead air. This doesn't replace the first fix. It's there for the gap that's always going to exist between how much you've practiced and how genuinely unpredictable a real conversation is.
What a safety net should and should not do
A safety net is only useful if it helps you say something true, in your own words, faster, not if it hands you a script to read. The difference matters both practically and ethically: a tool that surfaces a relevant point from your actual CV to help you organize your own thinking is fundamentally different from one that tries to answer for you.
Live Interview Help's overlay works during a real Google Meet, Teams, or Zoom call, listening to the conversation and surfacing a relevant prompt from your CV and the job description when you need it, quietly, without interrupting your flow. It's built to reduce the panic of an unexpected question, not to replace the answer you'd give with your own knowledge and experience.
