I feel like this is the biggest lie ever told in this industry. Do you, as an interviewer, not read resumes?
I read loads of resumes and the truth is more like everyone are terrible communicators. Especially software engineers. Most resumes are badly formatted, badly typeset, full of errors and give me confusing/contradictory details about what your job responsibilities were rather than what you accomplished.
Most peoples' resumes are so low-effort that they're practically unreadable and I'm trying to read between the lines to figure out what you're capable of. I might as well not be reading them because I'm trying to figure out what you've done, what you're good at and what motivates you and nothing you've given me on that paper helps me do that.
One of these days someone is going to figure out how to cross-polinate technology people and sales people in the office to smooth out each others' rough edges. Whoever does is going to revolutionize industry.
I think that's a mistake, personally. Each interviewer needs to make an independent decision and relying on the judgement of a screener early in the process is giving that person disproportionate weight towards hiring for your team. Usually that resume screener is someone in HR. Would you trust them to decide who your team hires?
Your posts do indicate that maybe there is a larger segment of folks who don't read resumes than I realize...My amount of rigor may only come after being involved in some catastrophically bad hiring decisions. Like someone I made the deciding vote to hire was stalking multiple employees, was a heavy drug user, did zero work of value and ultimately crashed and burned by getting arrested for coming at someone with a knife. For years HR wouldn't let us fire that person because of their protected class and multiple false claims they made against a large number of employees.
It's not. I've been in a number of interviews where the interviewer has told me straight up "I didn't read your resume. Mind giving me a second to give it a scan?"
To be fair, as you mention, resumes are horrible tools. They should only be used as a place to start a conversation, so does it really matter if the interviewer reads it in depth before starting the interview?
