Interactive Interviewer
The interviewer can see your work in the whiteboard and code editor to discuss your exact approach and ask specific follow up questions.








Realistic, real-time mock SWE and Quant interviews with an interactive interviewer. 100% free company tagged problems.
Accepted code does not prove you can interview. CodeGround trains the parts that actually move a candidate through the loop: speaking clearly, adjusting under pressure, implementing cleanly, and learning from the review.
The interviewer can see your work in the whiteboard and code editor to discuss your exact approach and ask specific follow up questions.
All problems on CodeGround are completely free. Practice and submit problems across company tagged, system design, AI coding, quant, and more without paying a cent.
CodeGround's assistant can interact directly with your workspace and highlight lines of code, point out mistakes, and more.
See what held up, what sounded hand-wavy, and what to practice next without digging through a generic transcript.
