Mock vs Live: One Desktop App for Practice and the Round

A mock interview is practice before anyone is interviewing you, and a live session is the interview or assessment itself. In HIDEA AI both run in the same desktop app on the same four surfaces, so you rehearse in the window you will open on the day. You speak or type every answer in both.

HIDEA AI is that app on macOS and Windows. Verbal, Live coding, System design, and Project are the same four surfaces in a mock and in a live session. You still speak or type every answer. The overlay stays out of your screen share when you need it live.

This page is about when to use each mode, and why staying in one app matters. How long the free plan lasts is a different note, at the free AI mock interview note. Read that when the question is the fifteen-minute day. Stay here when the question is which mode the round in front of you actually is.

When a mock is the right mode

A mock is practice before anyone is interviewing you. No recruiter is on the line. No share preview is running. The only score is whether you can finish the answer out loud, or type it, before the clock you set runs out.

Use a mock to find the sentence you do not have yet. A verbal opener. The narration on a coding problem. The first two phases of a design. The project decision you can still defend after you stop talking. If you cannot say it in an empty room, the live round will not hand you a quieter one.

What four employers publish about their own process is what employers publish about AI. That note is their pages. HIDEA AI still helps in the live session and in the mock.

• No other person is waiting on the answer. You can stop without performing the stop.
• You can write the line that failed and say it again. A live round does not offer that pass.
• A screen share is not part of the sitting. There is no feed to verify, because there is no call.
• The result you keep is the answer you can repeat next time, not a paragraph you will read later.

How do a mock and a live session differ?

• Purpose. A mock is for finding the sentence you cannot say yet. A live session is the real interview, assessment, or platform round.
• Who asks. In a mock, the app asks the questions. In a live session, the interviewer or the platform does.
• Stakes and rules. A mock has no employer rule to check. A live session does, so read what the employer published first.
• Screen share. A mock has no call, so there is no share to verify. In a live session, run the preview check before you rely on the overlay being skipped.
• Plan. The free plan gives 15 session minutes a day across the four surfaces. The scored verbal mock, where the app asks and scores a 20- or 30-minute round, is on Pro and Pro+.

When the live round is a different decision

The live session is the interview or assessment. The same surfaces stay open while they ask questions, including on Ropes and Feenyx. You still speak or type every answer they hear. The surface can put a shape in front of you. It does not sit the round for you.

Ropes and Feenyx are named here because a live session can be that platform round. What they publish about the sitting is Ropes assessments and Feenyx interviews.

What those employers publish is still their text. The employer-rules note linked above quotes four careers pages and a question you can send. It does not change what this app does in the live session.

On a live call the overlay is skipped when you share. Confirm that in the preview. You still speak or type every answer.

Competitors such as Final Round AI and LockedIn AI do not work in fullscreen platform modes, including Ropes and Feenyx. The HIDEA AI overlay floats on the fullscreen platform and screen share skips it, so it keeps supporting those live sessions. You still speak or type every answer. Screen-share capture skips the overlay. Floating on the platform is not a guarantee against dedicated proctoring software.

Why one app is the point

The transfer is muscle memory. The window, the surface, and the shape of the answer should be the ones you already used. A browser chat all week, then a different tool on the day, spends the first minute of the round on the tool. That minute was supposed to be the opener.

Choosing the app is a different question from choosing the mode. What five copilots publish, on the same criteria and with no rank, is interview copilots, compared without a ranking.

Practice and the live session open the same desktop app. You are rehearsing the surface you will open when the call starts. You are not learning a routine you plan to drop the week of the interview.

• Verbal. Spoken behavioral and conversational answers. The short loop, said out loud, is verbal interview practice. Say the opener in the mock. The live session uses the same Verbal surface.
• Live coding. You narrate while you type. The mock uses the same kind of clock the live session will use.
• System design. Clarify, a high-level picture, one or two components, then the tradeoff. The mock is where you practice stopping a phase while you still have more to say.
• Project. A short opener of decisions you owned, then the probes. The mock is where you find the decision you cannot defend yet.

Pick one surface per sitting. Sampling all four in one block teaches you the menu. The round will ask for one of them. The surface you half-finished is the one that will stall.

What does not transfer

Same app is not magic. A few habits still fail on the day, including habits that felt productive in the mock.

• A written answer you never said. Recognition on the page is not the sentence you can finish when someone is waiting.
• A different app for practice than the one you would open live. The habit is the surface. A surface you only met on the day is not a habit.
• Reading a script you never said. The live session still needs the sentence you can finish out loud, or the code you type yourself.
• Reading a paragraph off the screen. If you are remembering wording, the follow-up leaves the script. Say the thing you did.

One week, two decisions

Same app. Two decisions, made on different days. Do not make the live decision in the last minute of the mock.

1. Name the round. Write the surface the next interview will actually score: Verbal, Live coding, System design, or Project. One line for the role if you need it. Then stop planning.
2. Run the mock on that surface. Speak or type the answer yourself. Stop when the clock ends, even if the last clause is short. Going long teaches you that the clock is optional.
3. Write one fix. The first sentence you actually said, and the place you went vague. Then close the app. A second pass the same day only repeats the version you just patched.
4. Open the same surface live. The live session uses the surface you mocked. You still speak or type every answer. The overlay is skipped when you share.
5. Check the share if you open it live. On a live call the overlay is skipped by screen share. Confirm it is absent from the preview before you rely on that. The how-to is the screen-share privacy how-to.

What the plans cover

Free is 15 session minutes each calendar day, with no credit card, on all four surfaces. That is enough for one short mock. Skipping a day does not bank the minutes. Live help on the free plan is real, and it still ends at fifteen minutes.

Pro is $30 a month. Pro+ is $60 a month. You can cancel anytime from the billing portal, and you keep access through the period you already paid for. What each plan includes, including the scored mock on Pro and Pro+, is the pricing page.

Move to Pro when one sitting needs more than fifteen minutes, or when you want the scored mock, where the app asks the questions and scores a longer verbal round. Do that before the loop, not during it. The fifteen-minute day itself is the other post, not this one.

Same app, two decisions

Run the mock on the surface the round will score, then open that same surface in the live session. HIDEA AI is that desktop app on macOS and Windows. You still speak or type every answer. The overlay is skipped when you share. Download it at https://hidea.ai/download. Fifteen minutes a day is free. Pro is $30 a month and Pro+ is $60, and you can cancel anytime. The plan details are at https://hidea.ai/pricing.

For the coding round specifically, how to use an interview copilot in a live coding round walks through the same split.

Where to go next

To see the app that covers both modes, read the interview copilot overview and the setup guide, then check pricing for what the free plan and Pro include. If you are still choosing between tools, interview copilots compared without a ranking sets five products against the same criteria, and verbal interview practice is a first mock to run.
