I totally agree with you. I have been surprised by the lack of interest in any professional presentation by candidates. I actually had a guy show up in shorts and a camp shirt and say, I kid you not, “Sorry I’m late dood but this bitching bar downtown just opened and I gotta get back there. They got smoking sweet chicks and I think I can bag one.” The job was for a $100k+ hardware engineer. I hope he got the “chick” ‘cause he didn’t get the job.
I'm sure that we could swap plenty of horror stories.
