Optiver's India quant and trading interviews are famous for fast mental-math and probability tests before you reach any deep discussion.
In 2026 you should expect a timed arithmetic assessment (the well-known 80-in-8 style speed test), then rounds on probability, expected value, market-making games, and combinatorics. Optiver screens for raw quantitative speed and sound reasoning under pressure, so accuracy at pace matters as much as knowing the theory.
