Did you look at the source code for VTAM for example when you were working?
The architecture is how the bits fit together, not a detailed knowledge of
how the bits work individually.
Its exposed by means of MACROS, Control Blocks and Data Areas.
You need to know how the control blocks relate and interact and how zOS uses
them
However as you say its unlikely that some one who is young and inexperienced
is able to fill the bill. IBM is doing things to "speed" them on their way.
They publish a 13 volume collection of RED Books
http://www.redbooks.ibm.com/abstracts/sg246981.html?Open
which is designed to get zOS systems programmers going, in addition there
are still 5 volumes on the data areas for which oddly have MVS and zOS in
the title:-
z/OS V1R7.0 MVS Data Areas, Vol 1 (ABEP-DALT) IEA2D160 07/14/05 16:05:23
GA22-7581-09
z/OS V1R7.0 MVS Data Areas, Vol 2 (DCCD-ITZYRETC) IEA2D261 01/18/06 12:08:21
GA22-7582-10
z/OS V1R7.0 MVS Data Areas, Vol 3 (IVT-RCWK) IEA2D360 07/14/05 17:35:52
GA22-7583-08
z/OS V1R7.0 MVS Data Areas, Vol 4 (RD-SRRA) IEA2D460 07/14/05 17:34:43
GA22-7584-08
z/OS V1R7.0 MVS Data Areas, Vol 5 (SSAG-XTLST) IEA2D560 07/15/05 10:49:38
GA22-7585-08
I guess some one who has read and understood all that would have a pretty
good understanding of the internal architecture....
... but the probably by then they would no longer be "young"...
Dave
P.S. A google on "zos architecture course" has lots of hits as well....
PPS On a similar vein any one care to bet when the first job for some one
with 12 months experience of Windows/8 will appear...

My guess this is code for "he wants them as cheap as possible".
