3d High End Jobs

What software does the architect on HGTV’s “Hidden Potential” use to showcase their design ideas?
A 2007-06-27 job posting on NYASLA’s web site suggests it’s AutoCAD (see below), but previous Answers have suggested Maya. Have they changed recently? Are those the same package under two different names?
From the listing:
“HGTV’s Hidden Potential is looking for talented, motivated Jr. Architects and Designers AutoCAD operators to join our Design Team. This is a unique opportunity to work alongside our on camera architect and designer in helping them achieve their visions. We design a high volume of residences and at the end of the job, a Jr. Architect will walk away with amazing 3D animations and still renderings of their design work. It is a fun, fast-paced design environment.”
“The ideal candidate has an eye for design – structural and interior – is proficient in AutoCAD, and is able to contribute to the creative design process on a daily basis. One must be computer savvy as our design team continually uses various software tools and FTP sites…”
To be honest with you I don’t know what HGTV uses. However I know many architects and designers and most use AutoCad / Apple/ Macintosh /…as best design & photo software (they say) is compatible with this software/hardware combo.
