My first job out of undergrad was doing pre-sales on what was Mentor Graphics' (acquired) PADS PCB design tool.
As part of our jobs, our small group of people in their early 20s would handle this inbound phone number for NA and any voicemail that came in after hours. We'd do basic qualification, write up the lead and if it was good pass it to the inside sales rep who managed whatever region it came from.
I remember looking at the license holders and it seemed like everyone had at least a few licenses to that product. Siemens owns all that now.
Curious how PADS stacks up today, if anyone is familiar with the tool.
