Is this a real voice conversation or text-based?

It’s a real voice conversation. You speak naturally into your microphone and our AI interviewer responds in real time — just like a real interview. No typing required.

What types of interviews can I practice?

Five types, each with focused categories: Behavioral (STAR method), Technical (system design, algorithms, debugging), Case study (consulting-style), Leadership (people & stakeholder management), and Casual (get-to-know-you conversations).

How much does it cost?

Your first interview is free. After that, credits start at $0.15/minute with a subscription or $0.33/minute with a one-time pack. You only pay for minutes used — end early and keep the rest.

Do I need to install anything?

No. Everything runs in your browser. Just allow microphone access and you’re ready to go — no downloads, no apps.

Can I practice for a specific company?

Yes. Enter your target company and our AI will research it, then ask tailored questions about their products, culture, and industry.

How long is a session?

You choose — anywhere from 3 to 30+ minutes. You can also end early at any time and only use credits for the minutes you actually practiced.

What feedback do I get?

Detailed analysis including STAR structure scoring, filler word tracking, speaking pace, answer relevance, vocabulary variety, and an AI-powered answer rewriter that shows you how to improve each response.

Big Interview alternative

Big Interview lets you record video answers to pre-set questions. Instant Interview gives you a live voice conversation with an AI that listens and asks follow-ups in real time, plus quantified feedback on STAR structure, speaking pace, filler words, and answer relevance. Real practice, not a recording booth.

Live conversations, not recorded answers

Big Interview is good at what it does: structured curriculum, video recording, and body language review. But real interviews aren't scripted. They're conversations with follow-ups and curveballs you can't rehearse by recording yourself. Instant Interview fills that gap.

Why it matters

Recording answers isn't the same as having a conversation

Adaptive follow-ups

Real interviewers probe your answers. They ask "Can you tell me more about that?" or "What would you have done differently?" Big Interview can’t do this. Instant Interview does it every session.

Quantified scoring

Every session measures your STAR structure, speaking pace (120–160 WPM ideal), filler word rate, and answer relevance. You can track improvement across sessions with actual numbers rather than vague tips.

Company-specific prep

Enter your target company and the AI researches their culture, products, and typical interview style before your session. You end up practising the questions you’re most likely to actually face.

FAQ

Common questions

How is Instant Interview different from Big Interview?

Big Interview uses pre-recorded questions that you answer by recording a video of yourself. There are no follow-up questions and no real-time interaction. Instant Interview is a live voice conversation with an AI that listens to your answers and asks follow-ups based on what you said, which is much closer to how a real interview works.

Can I see myself on video with Instant Interview?

No. Instant Interview is voice-only, so you focus entirely on what you say and how you say it. If watching your body language on camera matters to you, Big Interview is better for that. Many candidates use both: Instant Interview for conversation skills, Big Interview for visual presentation.

Is Instant Interview cheaper than Big Interview?

Yes, significantly. Big Interview starts at $79/mo. Instant Interview starts at £7.99/mo for 60 credits, and you get 10 free credits on signup to try before paying. That makes it roughly 10x cheaper for regular practice.

Does Instant Interview cover behavioural interviews?

Yes. Behavioural interviews are one of five types available (the others are technical, case study, leadership, and casual). Each behavioural session scores your STAR structure across Situation, Task, Action, and Result, so you can see exactly where your answers need work.

Should I use both Big Interview and Instant Interview?

They work well together. Big Interview is strong for structured curriculum and reviewing your body language on camera. Instant Interview is better for realistic conversation practice with adaptive follow-ups and quantified scoring. Between the two, you cover visual presentation and verbal delivery.

Does Instant Interview ask follow-up questions?

Yes. Unlike Big Interview’s pre-set question list, the AI listens to your answer and asks follow-ups based on what you said. It probes for more detail, challenges weak points, and asks you to expand on interesting threads. That’s what makes it feel like a real interview instead of a recording booth.
