Negative ExperienceNo Offer

Process

Zoom call. The interviewer barely introduced herself and jumped directly into a question. I thought I answered decently well, but I kind of confused myself throughout the process and ended up getting a rejection.

Questions

I was basically implementing a stack machine, but it got more complicated, like how to transform a program and add instructions to add a feature or something.
