Interview Process
The interview consisted of a technical round focused on statistics and coding. The candidate was first asked to explain a theoretical problem involving particle decay. Specifically, they needed to calculate the probability of 100 particles still existing after 10 days, given that each particle has a decay rate of 1/2 per day.
Following the theoretical discussion, the candidate was required to write code in CoderPad. They were instructed to think out loud while writing a simulation. The input parameters for the simulation were the number of days (m) and the state of the particles (n), with the output being the state of the particles after the given time. The candidate was also asked to compare the simulation results with the theoretical calculations and compute confidence intervals. Additionally, they were questioned on how to calculate the decay rate if daily results were known.
