My first trip through this thread and having just hired a cad operator, my memory is a little more fresh on the subject. But first, I notice the negativity of having basic hand drawing skills. Search around the zone and you will find a heated debate that several of us had. Bottom line was the BASIC skills are very important.
The reason we had to hire a new cad operator was because the old one thought he knew how to draw (he didn't). Also as we have an in house standard of how things should be done, we expected the written guidelines to be followed.
Now having said that, what I look for is knowledge in the basic skills of operation of the cad program, so if you have some recent drawings, by all means lets see them as we can then get a feel for your depth of knowledge possibly. How set are you in your ways? That is to say, can you accept constructive and adapt to requested changes. Our shop is not typical in that we often receive Background material from Architects and then Xref this into our drawing and continue on.
In summary,
Demonstrate your experience.
Have a good attitude.
Be flexible as EVERY house is going to have their own way of doing things. Sometimes you will be able to enhance them and at other times they will be in-flexible about changing!
Oh and being able to do field sketching so it can be drawn up in cad is a very valuable skill!
