Interview Practice

How our AI mock interviews work

Practice under real pressure, get instant feedback, master follow-up questions, and track your improvement.

What It Does

HireHelix AI simulates real behavioral interviews with adaptive AI that probes deeper based on your answers - just like a real interviewer would. You get scored on four dimensions and can track your improvement over time.

Who This Is For

First-Time Interviewees

Never done a behavioral interview? Practice in a low-stakes environment first.

Career Pivoters

Changing industries or roles? Practice framing your experience for new contexts.

Experienced Professionals

Know your stuff but get nervous? Build confidence with realistic practice.

How a Session Works

1

Choose Your Setup

Select your target company (Amazon, Google, etc.) and role type. Premium users can also choose a specific competency to focus on.

2

Answer Questions

You'll receive 2-4 behavioral questions. Type or use voice input. The AI evaluates each answer and decides whether to ask follow-ups.

3

Handle Follow-ups

If your answer has gaps (missing metrics, unclear ownership), the AI will probe deeper - up to 3 follow-ups per topic.

4

Get Scored

When you finish, you'll see scores across four dimensions plus specific feedback on strengths and areas to improve.

Example: How adaptive follow-ups work

Initial Question

Tell me about a time you had to make a decision with incomplete information.

Your Answer

I led a project where we had to choose between two vendors without full pricing data. I gathered what info we had, consulted with stakeholders, and made the call to go with Vendor A...

F1

Follow-up 1

What specific metrics or criteria did you use to compare the vendors?

F2

Follow-up 2

You mentioned consulting stakeholders. What was YOUR role vs. the team's input in the final decision?

F3

Follow-up 3

What was the outcome? How did you measure whether it was the right call?

Why this matters: Real interviewers probe for specifics. Our AI does too - so you practice handling the pressure before it counts.

STAR Tips

On-screen guidance helps you structure your answers as you go.

Tips for Best Results

  • Prepare 5-8 real stories before starting. You can reuse them across different questions.
  • Use voice input to practice speaking - it's closer to real interview conditions.
  • Don't rush through follow-ups. They're designed to help you practice going deeper.
  • Review your scores after each session. Focus on the dimension where you score lowest.
  • Aim for 2-3 sessions per week. Steady practice beats cramming.

Timing Sweet Spots

Initial answer:

60-120 seconds (aim for ~90s)

Each follow-up:

20-45 seconds

Total per question:

Under 2:30 is ideal

Warning zone:

3:00+ means you're likely rambling

Our on-screen timer will nudge you at 2:00 and warn at 3:00 to help build this habit.

Frequently Asked Questions

How long is a practice session?

Most sessions take 15-25 minutes, depending on how many follow-up questions you receive. You can end a session early if needed, and your progress will still be saved.

What are adaptive follow-up questions?

Our AI analyzes your answer in real-time and asks follow-up questions based on gaps it detects - missing metrics, unclear ownership, or vague details. This mimics how real interviewers probe deeper. You'll get up to 3 follow-ups per topic.

How is my answer scored?

We score on four dimensions: Clarity (how well you communicated), Completeness (did you cover all STAR elements), Depth (level of detail and specifics), and Leadership (evidence of ownership and impact). Each dimension is rated 1-5 with specific feedback.

Can I practice for a specific company?

Yes! Select your target company before starting, and you'll get questions mapped to that company's actual values - like Amazon's Leadership Principles or Google's Googliness criteria.

Should I type or use voice input?

Voice input is more realistic since actual interviews are spoken. However, typing is fine if you're in a noisy environment or want to practice structuring your thoughts first. Many users start with typing, then switch to voice as they gain confidence.
