I applied online. The process took 3 weeks. I interviewed at Headlands Technologies (Chicago, IL) in Sept 2025
Interview
The process began with a coding challenge in C++ and then had a one hour long zoom interview one on one with a researcher. The response time was very quick between rounds, which was very appreciated.
