Practice interviews that actually push back
Round Zero runs a live AI interview (voice, avatar, or text) grounded in your job description and optional company research. It pushes back on vague answers, then scores you on a real rubric with transcript evidence.
- JD-specific questions that quote requirements from your posting
- Evidence-backed scorecard + thank-you email draft after every session
- Delivery coaching: pace, fillers, STAR structure (voice & text)
The JD calls out cross-functional influence with design and eng. Tell me about a time you had to push back on a product decision. What was at stake for you personally?
At my last role I blocked a launch when QA showed a 12% drop in activation on mobile. I owned the rollback call and we shipped a narrower fix two weeks later.
Walk me through how you diagnosed activation. What metric segment did you check first, and what would you have done if the drop was only on Android?
Live coaching: tighten your result metric upfront
How Round Zero prepares you
Interview prep is more than memorizing answers. We run the full loop: research, role-specific practice, and evidence you can act on before the real thing.
- 1
Target the role
Pick from 887+ presets or paste the job description you're applying to. Link a tracked application for one-click practice.
- 2
Research (optional)
Build a cited company brief, then practice with that intel wired into your session. Questions reference what the company actually cares about.
- 3
Live mock interview
Voice, avatar, or text. The AI interviewer rotates behavioral, situational, and role-specific questions, and pushes back on hand-wavy answers.
- 4
Score and close the loop
Rubric scorecard with transcript evidence, delivery coaching, a thank-you email draft, and smart questions to ask the panel next time.
Built for how real interviews work
Employers test motivation, past behavior (STAR), situational judgment, and role depth. Not whether you memorized “tell me about yourself.” Round Zero mirrors that mix.
Grounded in your JD
Paste a real posting or pick a role preset. Every question targets a specific requirement, not a generic list.
Research wired in
Run a company brief first; your interviewer weaves that context into questions the way a prepared panel would.
Live pushback
Adaptive follow-ups when answers are vague. Same pressure as a real hiring manager, not a chatbot reading prompts.
Evidence-backed score
Rubric grades with transcript quotes, delivery metrics, a thank-you draft, and questions to ask them next time.
Not a question bank. Not a chatbot.
Generic AI tools generate lists. One-way employer screens record one take with no follow-up.Round Zero is a live practice partner that adapts to your answers and your job description.
| Typical tool | Round Zero |
|---|---|
| ChatGPT or question lists | A live conversation that probes your actual answers, verifies resume claims, and escalates difficulty when you do well. |
| Employer async AI screens | Practice with follow-ups and funnel depth, the format most real panels use after the one-way recorder. |
| Generic mock interviews | JD checklist coverage, company research integration, preset rubrics per role, and scores saved per application. |
Common mock interview questions
The questions that come up in almost every interview, with what each one is really testing and what a strong answer contains. Role-specific sets (846 questions across 32 fields) sit on the category and role pages below.
- 1.
Tell me about yourself.
Why they ask it: Opens the interview and sets the frame. The interviewer is checking whether you can select what matters for this job rather than narrate your whole history.
A strong answer: A 60-90 second arc: where you are now, one or two proof points that match the posting, and why this role is the logical next step. Present, past, then future.
- 2.
Why do you want this role?
Why they ask it: Tests whether you read the job description or mass-applied. Weak answers are about what the candidate gets; strong answers connect to the work itself.
A strong answer: Two specifics from the posting or the company's actual work, plus an honest line about what you want to get better at here.
- 3.
Walk me through your resume.
Why they ask it: Checks that your story holds together and that the transitions were deliberate rather than accidental.
A strong answer: Chronological but fast, with a reason attached to each move and more time on the roles closest to this one.
- 4.
Tell me about a time you failed.
Why they ask it: Tests self-awareness and whether you own outcomes. Interviewers are listening for a real failure, not a disguised strength.
A strong answer: A genuine miss, what you specifically got wrong, the cost, and the concrete thing you changed afterwards that has since held up.
- 5.
Tell me about a conflict with a coworker or manager.
Why they ask it: Predicts how you behave when the team disagrees. The trap is blaming the other person.
A strong answer: The substance of the disagreement, what you did to understand their position, how it resolved, and what the working relationship looked like after.
- 6.
What's your greatest strength?
Why they ask it: Checks whether you know what you're actually good at and can prove it.
A strong answer: One strength that maps to the posting, plus a short example where it produced a measurable result.
- 7.
What's your greatest weakness?
Why they ask it: Tests honesty and whether you're actively working on something. Rehearsed non-answers ('I work too hard') read as evasive.
A strong answer: A real limitation that isn't core to the job, the system you built to manage it, and evidence it's improving.
- 8.
Tell me about a time you had to influence someone without authority.
Why they ask it: Almost every role depends on getting people who don't report to you to change course.
A strong answer: What you wanted, why they resisted, the evidence or framing that moved them, and what actually shipped as a result.
- 9.
Where do you see yourself in five years?
Why they ask it: Tests whether this job fits your trajectory, which is a retention question in disguise.
A strong answer: A direction rather than a title, and a line about the skills this role would build toward it. Vague ambition and rigid title-chasing both land badly.
- 10.
Why are you leaving your current job?
Why they ask it: Screens for red flags. Interviewers listen for how you talk about people you no longer work with.
A strong answer: Forward-looking and specific about what you're moving toward. Criticism of a former employer costs you more than it gains, even when it's deserved.
- 11.
What are your salary expectations?
Why they ask it: Checks whether you've done market research and whether you're in range before anyone spends more time.
A strong answer: A researched range with your target near the bottom of it, framed against the scope of the role. Deflect once if the posting has no band, then answer.
- 12.
Do you have any questions for us?
Why they ask it: The most under-prepared question in the interview, and the one that most changes the final impression.
A strong answer: Two or three questions about how the team actually works: what the first 90 days look like, how success is measured, what the hardest part of the job is.

Questions & answers
- What questions are asked in a mock interview?
- A good mock interview mirrors the real one: an opener like "tell me about yourself", behavioral questions about conflict, failure, and influence, role-specific questions drawn from the job description, and your questions at the end. Round Zero publishes 846 of them by field, with what each question tests and what a strong answer contains, and will ask any of them in a live scored session.
- How many mock interview questions should I prepare?
- Preparing six to eight strong stories beats memorising fifty questions. Most behavioral questions are the same few stories reframed, so build a story bank with real numbers in it and practice re-cutting those stories to whatever is asked.
- Is the mock interview free?
- Yes. 3 full scored interviews, no card. Complete scorecard every time, with the quoted evidence, a thank-you email draft and questions to ask the panel. Nothing is blurred and nothing is held back.
- How is this different from ChatGPT or question lists?
- Round Zero runs a live conversation that probes your actual answers, verifies resume claims, and rotates behavioral, situational, and role-specific questions, all grounded in your job description. It is not a static question bank.
- How many job roles can I practice?
- Round Zero includes 887+ predefined roles across engineering, product, sales, healthcare, finance, and more. Each role has a tailored job description and interview format. You can still paste any custom JD.
- Can I practice with company research?
- Yes. Build a cited company brief in Research, then launch a mock interview with that brief wired into the session. Questions reference what the company actually cares about.
- Voice, text, or avatar?
- Voice and text on every plan, free included, with the same scoring and the same delivery metrics (pace, fillers, STAR structure). Avatar adds camera pressure on Job Search. Text is great for focused prep on a lunch break.
- Can I practice for a specific job I'm applying to?
- Yes. Paste the job description, link a tracked application, or pick a predefined role. Your AI interviewer targets specific JD requirements and saves scores per application.
- How does this help with employer AI interview screens?
- One-way async screens record a single take with no follow-up. Round Zero practices the live format most panels use after that: follow-ups, funnel depth, and pushback on vague answers.
