After doing dev work for nearly two decades, I've been in presales for the last six years. I've definitely had a one or two intro calls with tech-savvy people who bullied their way past the BDR. These were smart people with good ideas, who had no idea what procurement at the enterprise company they just started working for even begins to look like, and it was 60-90 minutes none of us will ever get back, for a project that's never going to happen anyway.
I worked at a company where we jumped at every opportunity that we got, it's real nice to be somewhere now where there's a little more of a vetting process.
