Why InterviewSkool Wins
Voice Interaction, Not Just Text
InterviewSkool lets you speak to the AI interviewer in real time, just like a real FAANG interview. DevInterview.ai is text-only — you type your responses instead of speaking them.
Live Code Execution
Write code in the browser and run it against hidden test cases instantly. InterviewSkool shows pass/fail results and adapts follow-up questions based on your output. DevInterview.ai has no code execution.
Interactive System Design Whiteboard
Draw your architecture on an Excalidraw whiteboard while talking through your design decisions. DevInterview.ai only supports text-based system design descriptions.
Hiring Signal Scoring
Get a hiring signal from Strong Yes to No based on your performance across all dimensions. DevInterview.ai provides feedback but no hiring signal or signal-equivalent scoring.

Frequently Asked Questions
Is InterviewSkool better than DevInterview.ai?
For mock interview practice, yes. InterviewSkool runs full AI mock simulations with a live voice interviewer, code execution against hidden test cases, and interactive system design whiteboards. DevInterview.ai offers text-based mock interviews and DSA practice but lacks voice interaction, code execution, and whiteboard features.
How much does DevInterview.ai cost?
DevInterview.ai charges $19.99/month for unlimited access to its mock interviews, DSA practice, system design, and behavioral interview content. There is no per-session pricing — you pay a flat monthly fee. InterviewSkool charges ₹399 / $9.99 per interview with no subscription required.
Does DevInterview.ai have voice mock interviews?
No. DevInterview.ai is a text-based platform. You type responses to the AI interviewer rather than speaking. InterviewSkool offers real-time voice interaction where you speak to the AI interviewer just like in a real FAANG interview.
Does DevInterview.ai have a system design whiteboard?
No. DevInterview.ai offers text-based system design practice where you describe your architecture. InterviewSkool provides an interactive Excalidraw whiteboard where you draw your system design while talking through your decisions with the AI interviewer.
Which platform is better for FAANG prep?
InterviewSkool is better for realistic FAANG interview practice. It simulates the actual interview experience with voice conversation, live code execution, and system design whiteboards. DevInterview.ai is useful for text-based practice and problem-solving but does not replicate the real interview environment.
