If that's a criteria for you when looking for an employer, then that's your choice, but I personally would never expect such a thing.
The last time I had to interview (being an engineer), I was sent 7 resumes on a Monday for interviews being conducted on a Wednesday. I checked out any links they put on their resume, apps in the appstore, etc. If they did not feel they could be bothered to tell me about something, then it will remain a mystery to me.
