PracHub

PracHub is a web‑based platform that aggregates interview questions reported by candidates for more than four hundred companies. The database contains over ten thousand questions, each linked with a clear solution that explains the algorithm, outlines trade‑offs, and offers follow‑up prompts. The questions are grouped by company, role, difficulty, and interview type, making it straightforward to target the material to your needs.

To begin, you can either leave the filters blank and see the entire pool or select a specific company from the drop‑down. Once a company is chosen, a list of questions appears; each item shows the role it targets (e.g., Software Engineer, Data Scientist, Product Manager), the difficulty level (Easy, Medium, Hard), and the interview category (technical, product, data). Clicking a question opens a detail view that contains the problem statement, a code solution in a common language (Python is often used), a discussion of design choices, and suggested follow‑up topics. The solution pane can be collapsed, allowing you to try solving the problem on your own before revealing the answer. This mimicry of an actual interview scenario lets you practice articulating trade‑offs and probing potential extensions.

For focused practice, PracHub lets you add questions to a personal study list. The list is stored in your browser session and can be edited to remove completed items or reorder them for a custom review sequence. There are no downloadable files; all interaction happens in the browser, so you need only an internet connection. The platform also offers role‑specific prep guides for firms that appear on your personal list; the guides outline the typical interview process and highlight the key question types you are likely to face. However, the site does not supply a pricing structure, mobile app details, or progress‑tracking dashboards.

PracHub is well suited for candidates who want to practice authentic interview questions from real candidates, especially those preparing for roles in software engineering, data science, or product management. It is most useful when you already know the companies you plan to interview with; if you are looking for a general coding practice platform, the focus on company‑specific queries may feel too narrow. The tool does not provide an active community for discussion, and it does not offer automated analytics or performance tracking beyond simple question review.
