I've had one interview using Skype screen sharing where I had to import a toy project in my IDE and deal with some more "real-life" kind of tasks, and it was a good experience. Collabedit and the like are a bit limiting outside of Google-style algo questions.

I'd never install something like LogMeIn/TeamViewer though.

Showing my screen is one thing... I prefer a collabedit or something similar... I work on a MacOS computer... so even when apps are closed, notifications still show. I set my messages notifications to show the full message... including images... so even with Messages closed, if my wife SMS's me, it shows on my screen. I dont want to have to go shut off notifications for an interview process... and i shouldnt have to.

There are plenty of tools to share the code view in many IDEs.. there are sites and services dedicated to this. To have access to my entire desktop, INCLUDING control of my mouse/keyboard and installing software... I would have a hard time telling them not to go fuck themselves... because the level of disrespect in treating an adult like a child student is so high its painful...

I hate having to shut down notifications for screen shares as well, but I found out that there is a pretty easy way to mute them temporarily on macOS. Alt + click on the notification button (top right corner) and it will mute notifications.
