Send /start and enter your target position — Software Engineer, Product Manager, UX Designer, or any other tech role. Paste a job description for hyper-tailored questions.

Answer by voice

The bot asks a question and you reply with a voice message — just like a real interview call. Speak naturally. The AI transcribes every word instantly.

Get instant AI feedback

Receive a structured breakdown: content score, English clarity score, what you got right, what you missed, and the ideal answer. Then move to the next question or retry.

Features

Everything you need to interview with confidence

Built for engineers, designers, and PMs who take preparation seriously.

Voice-first practice

Answer by speaking, just like a real interview. Practising out loud builds fluency and confidence that typing simply cannot replicate.

Dual scoring: content + clarity

Every answer gets two scores out of 10 — one for technical accuracy and one for English clarity. Know exactly where to improve.

Ideal answer hints

After each answer you can reveal what a strong response looks like. Learn the model answer without being shown it prematurely.

Unlimited retries

Not happy with your answer? Retry up to 3 times per question. The bot tracks your best attempt, not your first.

FAQ

Frequently asked questions

Everything you need to know before your first session.

How does Tech Interview Coach AI work?
Open the bot on Telegram, tell it your target role (e.g. Software Engineer or Product Manager), and it generates relevant interview questions. You reply with a voice message. The AI transcribes your answer, evaluates it against a structured rubric, and replies with a score out of 10, your strengths, what you missed, and an ideal answer hint — all within seconds.
Do I need to install anything?
No. The coach runs entirely inside Telegram. If you already have Telegram on your phone, tablet, or computer, just open the bot link and press Start. No extra app, no account creation, and no credit card required for the free tier.
What roles and topics does it cover?
Tech Interview Coach AI covers all major tech roles: software engineers (frontend, backend, full-stack), data engineers, product managers, UX/product designers, QA engineers, and DevOps engineers. You can specify your exact target role and optionally paste a job description for tailored questions.
How accurate is the AI feedback?
The bot is powered by GPT-4o, the same model behind ChatGPT. It evaluates your answer against a structured rubric covering technical accuracy, depth, real-world examples, and communication clarity. Scores correlate well with what a senior interviewer would expect. Like any AI tool, it is best used as a rigorous daily practice partner rather than the final arbiter.
Is my voice data stored or shared?
Your voice recording is sent to OpenAI Whisper for transcription only and is not retained by OpenAI beyond the API call. We store only the text transcript and your score. We never sell your data to third parties. See our Privacy Policy for full details.
What is the difference between Free and Pro?
Free users receive a one-time welcome pool of 5 questions, then 3 questions per week indefinitely. Pro users get 100 questions per month — enough for a full daily practice routine. Both tiers include voice answers, AI scoring (content + English clarity), ideal answer hints, and follow-up questions.
How do I upgrade to Pro?
Send /subscribe inside the bot. A secure Telegram Stars payment prompt appears. Stars are Telegram's built-in digital currency and can be purchased directly inside the Telegram app with a credit card, Apple Pay, Google Pay, or crypto. The subscription renews monthly and can be cancelled any time from Telegram Settings → My Stars → Subscriptions.
Can I use it on a desktop or laptop?
Yes. Telegram has native apps for Windows, macOS, and Linux, plus a full web app at web.telegram.org. Voice messages work on all platforms. The coach behaves identically everywhere — you can start on your phone and continue on your laptop without losing progress.
What language is supported?
Currently English only. The AI separately scores your technical content and your English communication clarity — useful if English is not your first language, as you see exactly where vocabulary, grammar, or structure could be improved.
How do I cancel my Pro subscription?
Go to Telegram Settings → My Stars → Subscriptions and tap Cancel. Your Pro access stays active until the end of the current billing period. No forms, no support tickets, no questions asked.

Your next interview is closer than you think.
