Not actually an interview, but a step before: Had to write code on google sheets, no online IDE, **GOOGLE SHEETS**. Had two questions: 1) is the string of brackets is correct (you know, "(())[]" etc.); 2) shortening a code. I was naive, thinking they want to see "how I am thinking". NO. They actually copy paste the code and expect it to run. After being written in google sheets. Where they can tell if you paste code. Very unprofessional. No code riview will be offer, nor will be given if asked for, since no-one actually reads the code.
