If you are preparing for an interview at Google, Stripe or OpenAI, you eventually hit the same question: what do they actually ask? LeetCode gives you algorithms, Glassdoor gives you fragments. PracHub promises to combine the two, with questions sorted by company, role and round. This review covers what it offers, where its limits are, and who gets real value from Premium.

PracHub at a glance
PracHub is an English-language platform for technical interview preparation. At its core is a question bank that candidates fill after their interviews and PracHub then edits. Around it you find experience reports, courses, company guides and personalized cheatsheets.
The numbers at the time of our test:
| Area | Size (September 2026) |
|---|---|
| Interview questions | about 11,000 from 542 companies |
| Experience reports | 4,086 |
| Company guides | 804 guides covering 771 companies |
| Courses | 12 courses with 794 lessons |
| Target roles | Software Engineer, Data Scientist, ML Engineer, Product Manager, Data Engineer |
The question bank: the heart of the platform
You can filter the question bank by seven criteria: company, role, category, difficulty, interview round, seniority and your own progress status, so you can search for something as specific as “Meta, senior, onsite, system design.”
Coding tasks make up the largest share, alongside plenty of questions on team fit, conflict and leadership, each with expected answer components and likely follow-ups. Many questions have separate tabs for the problem, a STAR-based model answer, and community answers.
Data scientists miss one important tool, though: tasks like computing a precision-recall curve appear as plain text with no runnable notebook. For tasks like this you still need a local Jupyter setup or Google Colab.
Courses, company guides and cheatsheets
Under “Learning”, PracHub offers 12 courses with 794 lessons in total, from Practical Python to system design casebooks to five courses on machine learning and AI. Every course opens with a few free lessons so you can judge quality before paying.
The company guides are the strongest feature in our view: 804 guides for 771 companies, with a topic breakdown, likely questions, a round table, and a prep plan. Explanations of company-specific formats stand out, like Stripe’s “Bug Squash” round. Quality tracks the available data, so smaller companies with few reports get more general guides.
Cheatsheets give you a study overview for a specific company and role, for example “OpenAI Software Engineer,” organized by stage and topic with architecture diagrams and study-time estimates. The first two sections are free, the rest requires Premium.
Do the questions really come from these companies?
No company publishes its interview questions officially, and PracHub is no exception. Everything comes from candidate reports, some of it clearly rewritten. Our guide on company-specific interview prep explains how to judge reliability.
What PracHub cannot do
PracHub is a knowledge platform. Nobody listens while you explain a solution or tells you if your STAR story is convincing. Applying in Germany adds more gaps: the platform is entirely in English, and the guides focus on US companies, trading firms and big tech, with almost nothing on the German-language HR interview or salary negotiation.
Pair PracHub with real interview simulation. Our comparison of mock interview options shows how peer platforms, AI tools and professional coaching differ.
How much does PracHub Premium cost?
PracHub sells Premium in three billing periods, all with full question bank access, detailed solutions, community discussions, every course and an AI mentor with up to 50 sessions per day.
| Plan | Price | Per month |
|---|---|---|
| Monthly | $27.99 per month | $27.99 |
| Quarterly | $79.99 every 3 months | $26.66 |
| Yearly | $119.99 per year | $10.00 |
Prices in US dollars as of September 2026. PracHub presents them as discounts on higher list prices, so they may change.
The quarterly plan saves almost nothing over paying monthly. If your prep might run longer than three months, the yearly plan costs less than two quarters, and beats the monthly plan from month five on.
Pros and cons
| Pros | Cons |
|---|---|
| Very large, current question bank with precise filters | Origin of individual questions cannot be verified |
| Detailed company guides with round-by-round breakdowns | Guide quality depends on how much data exists |
| Behavioral questions with model answers and follow-ups | No notebooks for data science tasks |
| Strong courses on ML, GenAI and AI agents | Little content on German employers |
| Generous free tier for testing | No feedback from real interviewers |
| Personalized cheatsheets per company | Coverage skews toward US companies |
| Yearly plan works out to only $10 a month | Monthly plan is expensive by comparison |
Verdict: who should use PracHub?
PracHub is worth it above all when you have a concrete interview coming up at a large international tech company. The company guides and filterable question bank save you hours of digging, and the platform is particularly strong for ML engineers and anyone targeting AI companies like OpenAI or Anthropic. It is a weaker fit if you mainly apply to German companies, or if you are just starting out.
How we would approach it: start free, read the guide for your target company, and work through the free lessons. The monthly plan covers a single interview; a longer job search justifies the $119.99 yearly plan.

FAQ
Is PracHub free?
Partly. You can browse the question bank, the interview experiences and the company guides without paying. Every course opens with free lessons, between 2 and 14 depending on the course. On the cheatsheets, the first two sections are free. Individual premium questions, the remaining course lessons and the rest of each cheatsheet require PracHub Premium. Premium costs $27.99 per month, $79.99 per quarter or $119.99 per year (as of September 2026).
Do the questions on PracHub really come from the companies?
Nobody outside the company can prove that. PracHub collects questions from candidate reports, not official question lists. We explain how to judge reliability and what signals to look for in our guide on [company-specific interview prep](/en/guides/company-interview-questions).
Is PracHub useful if I am applying for jobs in Germany?
For international tech companies with offices in Germany, such as Google, Amazon, Microsoft or Stripe, PracHub is a strong resource because their interview loops look similar worldwide. For German Mittelstand companies, corporates or local startups you will find very little material. Topics like the German-language HR interview or salary negotiation by German standards are not covered.
Does PracHub offer interactive notebooks for data science?
No. Data science tasks are shown as text with community answers. There is no runnable Jupyter-style notebook. The only place where you can execute code in the browser is the editable Python console in the Practical Python course.
What is a good alternative or complement to PracHub?
For pure algorithm practice, LeetCode is still the standard. For interview simulation with feedback you need real people, either peer platforms or professional mock interviews. PracHub cannot replace that practice because nobody evaluates your answers live. At CodingCareer, former FAANG interviewers run mock interviews in English and German.
