Colloquio
The role was a causal inference-heavy pricing role. Started with a HR phone screen followed by 4 interviews over two rounds.
The first technical round involved foundational causal inference theory questions followed by a pair programming component that involved refactoring ML model code.
The final round consisted of 3 interviews that involved classical ML theory, a case study and behavioural questions respectively.
The entire process took nearly 6 weeks. I was strung along for a few weeks after the final round by HR before I ultimately got a rejection.
