Perplexity builds an AI-powered answer engine, so its software engineering interviews mix strong practical coding with questions on search, retrieval, and systems that serve LLM-backed features at low latency.
In 2026 candidates in India (remote or via its growing presence) should expect coding rounds on real problems rather than trick puzzles, plus design discussions on retrieval, ranking, caching, and API reliability. The bar favours fast, high-quality shippers who reason clearly about latency and cost.
