I visited a Chinese PCBA assembler.
In a room by itself was a Pick & Place machine hard at work Pick & Placing.
In the main factory was a long table with workers (all women AFAIR) thereat=
..
Each worker had bins with two SMD parts in. (May have been some with more -
I recall all having two)(2008?)
The first received a bare PCB and using tweezers placed as many parts on
the board as required manually and moved the board to the next in line
(left to right).
Faaast.
At the end of the table the loaded boards were placed on a conveyer leading
to a wave soldering machine.
Presumably the load time per worker was standardised to maintain even flow
(either more parts for some or maybe two or more workers for parts with
multiple examples loaded. Photos somewhere)

Presumably the jobs were assigned to the automatic or manual "machines"
depending  on which was faster for the component mix.

Nearby women were installing wiring into boards. I recall one lady taking a
6 wire cable with the leads formed 'just so' and placing all 6 leads into
holes in the board simultaneously.
Watching it being done was mind bogglingly amazing.
