See my other response on that. No company is holy, all of them have a lot of uninteresting stuff going on.
It just keeps coming down to, just saying there's a job and just saying "show me something" is not going to get you a serious response, unless you are a renowned guru of whatever subject it is about, leading the worldwide company in that area and you have droves of fanboys drooling over the opportunity to work for you regardless the parameters. (Call it the Jobs or Gates effect)
If you say, "Hey, we have 5/10/20/50 jobs over at my company, they are all in Altium design work, they cover any range between this and that subject, we are looking to hire professionals and starters, but a minimum of half a year of Altium experience is required. Cannot tell too much about the job contents, but if you think you might be interested send me a message with your resume, not older than 6 months and at least one example of something you designed in Altium with some decent detail (source files not always required)." That says EVERYTHING you have posted, nothing you can't post, but it does show people that you or your company is being serious about it.
And to be honest, who you are, what company you work for, all irrelevant to me if I read a message like that, because your company says nothing about the people I will have to be working with, so it's going to come down to meeting/skyping anyway. But scraping together what little of my Altium work that's not been sold off or done under NDA isn't something I can do in 5 minutes, so it's not something I will do as a response to a message that didn't even take 5 minutes to write, nor to the response "show your work". Even if you were my closest personal friend and I knew everything about you, that wouldn't do it for me.
I'm just trying to explain how it works our side of the screen, what you do with it is up to you, but I'm not trying to upset you or annoy you, I'm trying to help you create ads that will get less of the "heh, here's my junk, job now" from the jokers and more of the "Awesome! Who do I call?" from the real pros.
