Reviews
A genuinely useful tool! I quickly found a practice partner, we rehearsed typical questions and tough cases together. Prep was efficient and low-stress — and it ended with an offer! Huge thanks to the creators; the bot really helps build skills and confidence before interviews. Highly recommend! 🚀
Thank you 🙏 It really helped with prep and landing a job 🔥
An absolute gem! 🔥 Saved my interview prep. Studying alone is hard; with a partner it feels like a real interview. We drilled algorithms, debated architecture, and fixed each other's mistakes. I felt much calmer walking into the employer meeting. Result: offer received! If you're tired of prepping in a vacuum — try it! 🙌
Great bot! Helped me find a partner for IT interview prep. Studying together was far more effective, and I passed the interview and landed a job. Thank you ☺️
Interesting project! Connecting developers is exactly what we need right now.
A useful trainer for IT interview prep 🔥🤙
Awesome bot — great for finding practice partners. Recommend.

Frequently Asked Questions
Answers to the most popular questions about the IT‑Career‑Gym platform
IT‑Career‑Gym is a platform for IT professionals and employers: it matches you with a partner for mutual mock interviews, offers quizzes on technologies and languages, a participant rating, and job and resume postings. It runs as two interfaces over shared data — the website and a Telegram bot.
You create a request: pick a direction (IT or a foreign language), a specialization, your own grade and the grade range for your partner. The system looks for a counterpart request that suits both sides and, once a pair is found, shows the contact in your account on the website (My subscriptions). You may also get an email or Telegram notification depending on your settings. You run the interview yourselves — time and format are up to you.
Click "Register" in the top menu, enter your name, email and password, and pick a role — specialist or employer. A confirmation code is sent to that address. You can also sign in with Telegram, in which case no password is needed.
No — Telegram is not required. Registration, partner search for mock interviews, vacancy matching, quizzes and the leaderboard all work on the website. When a pair or vacancy match is found, you see it in the header bell and in your account (My subscriptions, Match history). You can link Telegram in your profile for messenger alerts — it is optional.
The rating is the sum of points from quizzes, pet projects and matches. More practice moves you up. Reviews do not affect it.
IT interview courses and guides: mocks, System Design, C4

FAQ
Price, Stepik vs our guide, signup, and what to do after a course.
The IT Career Gym guide on this site is free. The two architecture courses are on Stepik — price and access live there. On this platform you can open the list, find a mock partner, and take quizzes without buying a “course pack”.
The guide is how to run a paired mock: IT section, languages, a walkthrough checklist. Stepik hosts full courses on System Design and the C4 model. Different formats — we do not glue them into one “learning path”.
You can read the on-site guide and open Stepik without an account. Finding a mock partner or taking a quiz on IT Career Gym needs registration.
Do not leave it as a “read later” tab. Find a partner on the match page or run a quiz. System design sticks when you explain the diagram out loud.
Not yet — we do not draw empty cards for those roles. Security, FDE, and hiring are covered in the blog. If another real course appears, it will land in this list.

Vacancy matches
Filters → a search request → matching. We notify you when a job fits.
Sign in to create a vacancy search request. How matching works is explained below, no account needed.
How vacancy matching works
IT‑Career‑Gym looks for jobs against your request: role, stack, grade, work format and city. You can still browse the job catalogue — the request keeps working when an employer posts something new.
Applications send your base resume. The platform does not call HR for you: match, notification, vacancy card — you decide whether to apply.
Requests and notifications
Active requests live under My searches: pause them without dropping history. Matched jobs collect in a separate list — handy after a few notifications.
Email, Telegram, or both — pick a channel in your profile. While a search is running you may get a short reminder that the request is still on.

How to manage vacancy search requests
My searches holds your requests: role, stack, grade, format and city. Pause a request and the matched jobs stay in history.
A new filter set is built under vacancy matches. Each card shows whether search is running and how many jobs already fit.
When a request finds a job
Matched jobs open from the request card and also collect in match history. Applications send your base resume — the platform does not call HR for you.

Step-by-step partner matching for a practice IT or language interview
Чтобы создать заявку на поиск партнёра, войдите в аккаунт. Описание сервиса ниже доступно без регистрации.
Как работает подбор партнёра
IT‑Career‑Gym helps you find a partner for a practice interview: pick a track (IT or languages), specialization, your grade, and the grade range you want. The system searches website and Telegram requests and notifies you in the account bell when a pair is ready.
Собеседование вы проводите сами — в удобное время и в выбранном формате. Платформа нужна для мэтча, напоминаний и истории, а не для замены живого разговора.
Подписки и история
Активные заявки живут в разделе «Мои подписки»: их можно отключить, пока партнёр не найден. Грейд на карточке не меняется — новую заявку собирают в поиске. Прошедшие моки и отзывы о партнёрах собраны в «Истории».
Такой цикл — поиск, мэтч, практика, фиксация результата — помогает готовиться к реальному интервью без лишней бюрократии и с понятным следующим шагом.

Активные заявки на поиск партнёров по собеседованиям
Чтобы видеть и управлять заявками на поиск партнёра, войдите в аккаунт. Как устроены подписки — ниже, без регистрации.
Как управлять подписками на поиск партнёра
В «Моих подписках» хранятся заявки на поиск пары для мок-собеседования: специализация, свой грейд и диапазон грейда партнёра. Подписку можно поставить на паузу или удалить — грейд на карточке не редактируется.
Новую заявку с другими грейдами собирают в разделе поиска партнёра. Каждая карточка показывает, идёт ли поиск, и можно ли повторять уже найденных людей.
Когда подписка находит партнёра
Найденные люди открываются из карточки заявки. Прошедшие моки и отзывы живут в истории собеседований. Собеседование вы проводите сами — платформа нужна для мэтча и напоминаний.
Куда писать о мэтче — почта, Telegram или оба канала — настраивается в профиле. Пока подписка активна, можно получить короткое напоминание, что заявка ещё ищет пару.
Quizzes
Test your knowledge in the chosen sub-specialization: express, deep, and thematic formats.
29,590 questions across 1,499 sets in the bank — enough for lots of practice.

Форматы квизов на IT‑Career‑Gym
На платформе можно проверить знания по Backend, Frontend, DevOps и другим специализациям. Экспресс — 5 вопросов, глубокий — 20, тематический — 15. Число вопросов вручную — только в расширенном режиме.
Экспресс подходит для разминки перед собеседованием, глубокий — для системной оценки, тематический — чтобы закрыть конкретный пробел. Сложность подстраивается по ходу: после верного ответа следующий вопрос сложнее. Часть вопросов — свободный текст. Результаты попадают в историю попыток и влияют на рейтинг.
Откройте экспресс, глубокий, тематический квиз или историю попыток. Расширенный режим на этой странице позволяет выбрать блок и число вопросов вручную (до 50). Рейтинг снижается, если копировать вопрос или уходить со страницы.
Daily challenges
Three tasks for today. Tomorrow a different set: quizzes, matches, resume, a pet project or a referral.
Почему стоит проходить челленджи каждый день?
Регулярная практика — ключ к IT‑собеседованиям. Каждый день три задания: квизы разных форматов, мэтч со специалистом или вакансией, резюме, пет-проект или реферал. Прогресс считается за реальные действия на платформе.
На IT‑Career‑Gym челленджи связаны с квизами, пет-проектами, мэтчами специалистов, мэтчами вакансий, резюме и рейтингом. Набор карточек меняется каждый день.
Частые вопросы
Что такое ежедневные челленджи в IT‑Career‑Gym?
Это три задания на сегодня: пройти квиз нужного формата, найти мэтч, откликнуться на вакансию, обновить резюме или пет-проект, подняться в рейтинге или отправить рефералку. Карточки меняются каждый день, прогресс идёт с реальных действий, а не с чеклиста.
Как заработать XP и удержать стрик?
Закройте карточки дня — за каждое задание начисляется бонус XP. Стрик растёт, если вы активны каждый день. Пропуск дня сбрасывает серию. Энергия списывается только за старт обычного квиза.
Нужно ли платить за челленджи?
Нет: задания бесплатны для специалистов. Super даёт безлимит энергии на квизы, но не прячет челленджи. У работодателей челленджей нет.

Plans for candidates
Reviews
An absolute gem! 🔥 Saved my interview prep. Studying alone is hard; with a partner it feels like a real interview. We drilled algorithms, debated architecture, and fixed each other's mistakes. I felt much calmer walking into the employer meeting. Result: offer received! If you're tired of prepping in a vacuum — try it! 🙌
A genuinely useful tool! I quickly found a practice partner, we rehearsed typical questions and tough cases together. Prep was efficient and low-stress — and it ended with an offer! Huge thanks to the creators; the bot really helps build skills and confidence before interviews. Highly recommend! 🚀
Great bot! Helped me find a partner for IT interview prep. Studying together was far more effective, and I passed the interview and landed a job. Thank you ☺️

Вопросы и разбор ответов — как на IT-собеседовании.
Чат доступен на тарифах кандидата от 499 ₽/мес. Страницу можно читать без подписки.
Текстовый мок: вопросы, разбор ответов и слабые места по вашему стеку.
Можно прикрепить файл резюме — в запрос уйдёт текст без email и Telegram.
Чем помогает ИИ‑ассистент
ИИ‑ассистент IT‑Career‑Gym — отдельная страница с чатом: Coach готовит к собеседованию, Resume Reviewer разбирает резюме под ATS, Career Path строит план обучения, Quiz Generator предлагает вопросы по слабым темам, Match Helper подсказывает партнёра для мока.
Ассистент опирается на ваш профиль, историю квизов и загруженное резюме. Ответы приходят структурированным markdown со списками и подсветкой кода. Это тренировка на платформе, а не замена живого интервью.
Как связан с квизами и мэтчами
На поиске партнёра есть тизер с переходом в режим Match Helper. В квизах кнопка «Спросить ИИ» открывает чат с темой. Разбор файла — со страницы резюме. Практику закрепите в ПЭТ‑проектах.
Доступ к чату — на тарифах кандидата от 499 ₽/мес (10 / 30 запросов в день или безлимит на год). Описание режимов на этой странице открыто всем, в том числе без регистрации.
Частые вопросы
Что умеет ИИ‑ассистент IT‑Career‑Gym?
Ассистент помогает готовиться к IT-собеседованию: генерирует вопросы и проводит текстовый мок, разбирает резюме под ATS, строит карьерный план, предлагает квизы по слабым темам и подсказывает, какого партнёра искать для мока.
Нужна ли платная подписка для ИИ‑ассистента?
Да: чат доступен на тарифах кандидата от 499 ₽/мес. На базовом тарифе страница открывается с описанием возможностей и предложением оформить план. Лимит запросов: 10 в день на месяц, 30 на квартал, безлимит на год.
Как ассистент связан с квизами и мэтчами?
Из квиза можно нажать «Спросить ИИ» — чат откроется с темой и форматом. В подборе партнёра тизер ведёт в режим Match Helper. Сгенерированные вопросы можно сразу продолжить в разделе квизов, а заявку на мэтч — подтвердить кнопкой в чате.
Безопасно ли загружать резюме в чат?
Файл обрабатывается на сервере платформы и не попадает в публичный каталог. В промпт к модели уходит текстовый фрагмент без email и Telegram. История диалогов видна только в вашем аккаунте.
На каких языках отвечает ассистент?
На языке вашего сообщения — русском или английском, как интерфейс IT‑Career‑Gym. Ответы структурированы: списки, заголовки и подсветка кода.
