Optiver - Graduate Quantitative Researcher (2024 Start)

Can you solve this puzzle?

An ant leaves its anthill in order to forage for food. It moves with the speed of 10cm per second, but it doesn’t know where to go, therefore every second it moves randomly 10cm directly north, south, east or west with equal probability.

1. If the food is located on east-west lines 20cm to the north and 20cm to the south, as well as on north-south lines 20cm to the east and 20cm to the west from the anthill, how long will it take the ant to reach it on average?
2. What is the average time the ant will reach food if it is located only on a diagonal line passing through (10cm, 0cm) and (0cm, 10cm) points?
3. Can you write a program that comes up with an estimate of average time to find food for any closed boundary around the anthill? What would be the answer if food is located outside an area defined by ( (x – 2.5cm) / 30cm )2 + ( (y – 2.5cm) / 40cm )2 < 1 in coordinate system where the anthill is located at (x = 0cm, y = 0cm)?

WHAT YOU’LL DO:

Quantitative Research acts as the foundation upon which Optiver’s trading activities are built. Our research teams – experts with MSc and PhDs in a variety of STEM subjects – utilise a scientific approach to research and design our world-class trading algorithms. This means applying and developing state-of-the-art stochastic models to price options and predict market volatility, as well as utilising Monte Carlo methods to determine how to perform differentiation on discrete realisations of stochastic processes. It also means developing statistical arbitrage strategies by working with petabytes of low latency, high-frequency market data sets, an extensive high-powered computing back-testing framework and much more.

Optiver Researchers believe in academic discourse, and therefore invite their teammates and Traders to challenge each hypothesis. Can it be mathematically improved? Does it pose a potential risk? Does it exploit a market behavioural pattern? Can is sustain its output goals? Constant testing, analysis, refinement and innovation ensures our quantitative models remain at the cutting-edge of constantly evolving capital markets – you will play a key role in keeping us there.
