Voice interviewer

The AI speaks to you and listens to your answers. No typing back and forth — talk through your thought process naturally, like a real phone screen.

Write & run code

Full editor with Python, JavaScript, Java, C++, Go. Execute your code and see output. The AI watches your solution and gives real-time feedback.

Draw diagrams

Whiteboard for system design. The AI sees your architecture and discusses trade-offs, scalability, and failure modes — just like a real interviewer would.

Real company question bank

Vetted interview questions reported by candidates at top tech companies — each with detailed solution walkthroughs, complexity breakdowns, and interview tips.

Scored evaluations

After each session, get a detailed pass/fail evaluation scored on problem solving, communication, code quality, and more. Know exactly where you stand.

PM & product rounds

Product sense, prioritization, go-to-market, metrics, and PM system design. The AI plays the role of a product interviewer and challenges your thinking.

Perplexity onsite — LRU Cache, Trie puzzle, then nested transactions. Process was chaotic but questions were fair.

Netflix asked me to build a concurrent job scheduler. Worker pools, retry logic, dynamic scaling.

Seeing the in-memory KV store with transactions everywhere. Anthropic, Perplexity, Stripe all asked it.

What people are saying

Real feedback from engineers who've used OnsiteToOffer to prep. Identity kept anonymous for privacy.

I used this the week before my Anthropic onsite and the system design practice was uncannily close to what I actually got asked. The AI interviewer pushed back on my design the same way a real interviewer would. Got the offer.
