I see people at my office (and different companies!) saying they quit Slack/Whatever because they were getting bombarded by notifications... They had the option to notify on all messages. ¬¬
Even then, come on, I cannot believe experience hasn’t taught most of you how to handle quick interruptions. I usually just quick look at the notification to see if it’s really urgent. Otherwise it may be 7-10 minutes until I actually check the application, in case I’m doing some heavy thinking/coding session.
There are true interruptions like constant notifications, people physically talking to you about other things, and stuff, that while you cannot really tune them all out, you should be able to handle better with 2-3 years of experience. I read a lot of people on these forums with many more years not being able to cope with that.
I will die still unable to believe it was the norm, and not the exception :(
