On the initial call, the screener told me that the coding interview would be a series of coding questions on a certain skills-testing website, so that is what I prepared for. It wasn’t that at all— the interviewer plonked me down in an empty online environment that I wasn’t familiar with and basically said “build a web app, go” with very little guidance. I wasted too much time trying to figure out how to import different packages into the environment while the interviewer was very unclear on if that’s what he expected me to do or not. Then he said “time’s up” and was not interested in hearing any more about my thought process.
