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.
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.”
