and from friends who have gone back to analog I have not heard any complaints or any issues in regards to it. But as for someone who started from zero on glass... no clue
Realistically whether you have been trained on glass cockpit trainers or normal GA Cessna 150 cockpit instrumentation, should make no difference to a prospective employer. An artificial horizon in a glass cockpit Seminole or Cessna 172 is just a pretty little coloured instrument which displays the same basic attitude information as 1976 Boeing 737 artificial horizon or a 1986 Cessna 210 artificial horizon. Same with the HSI. There is nothing mysterious about glass cockpits and you should have no trouble interpreting attitude or heading information with either presentation.
