regarding autosaves:
they only delete if you have the permissions set on the folder they are created in set to permit them to be deleted 🙂
after i needed a few autosaves that autodesk decided i didn't need because cad closed as expected, i said ok, well we'll just change the permissions on that folder and solve that problem.
Why dont you sit them down at a CAD station with a DWG adn tell them they have 20 min to xref the ttbl.dwg and the back ground. then thell them you want them to insert a few blocks and do some drawing. If they get 1/2 to 3/4 done with what you want them to do and do it correctly have them come back for a secont interview. Being CAD smart and being able to answer some stupid questions that you want them to answer to see if they know enough to take your job is kinda backward if you ask me.
yes it is, it is too much...i worked on complex things ...but i tell you you must be really a knowledgeable freak to know all this... they are mostly not necessary to memorize for even complex projects with iLogic Parts...
if you have a comfortable base when facing a specific problem you check for solution on a forum or in the help.. if you have a good understanding of the explanation how to do it (use of specific technical language,software language understanding)you must be able to solve most of the problems.
I suggest recruiters, try a version of explaining the candidate how to do the test drawing( not necessary he has to do it the way you hint them but in case he has a blockage because of nervousness you can overcome it by giving them a way out ,in case of a draftsman interview) if they can grasp what you hint them then you see immediately that they know what you mean, or they might come up with an other solution meanwhile... and knowledge is not lost in the air just because the candidate being too nervous about performing good in an interview.
Example: create a part :a cylindrical part with certain diameter, 4 holes in it... create another part with d1, d2, d3 dimensions with a hole in it for the first cylindrical part created before.. arrange them in certain assembly . Explain a way how they could create the two sketches and how to assemble them in an assembly , using what way of constraining.
Ask them to create a drawing of the assembly , the 3 main views, a section and an isometric view... Adding a part list ( for intermediate candidate using the given dimensions in the sketch) they should be able to annotate the drawing too.
