Currently, I am a data scientist, but prior to that I was an air traffic controller (ATC). ATC training was brutal. You come in at 0530 for work/training, and you better be ready for a simulator first thing in the morning. Make a mistake get ready to be berated in front of everyone, and be scheduled to work the weekend. If you did well, you got to control real planes that day and you better perform exceptional while answering your trainers questions or forget controlling tomorrow. Questions would include, what is the separation between a heavy and small on final inside the approach gate? What is the radial and DME for xxxx point? What ABQ center's frequency?
We treated everyone the same - men and women. Women would often cry, yet they understood they weren't being treated differently from their male counterparts as every trainee was treated as s*. We had a 20% success rate with roughly 2 years of training. When you became a certified controller, it was a big deal and for males, every controller in the facility would punch the metal ATC badge into your chest the day of your final rating- it was a rite of passage.
Men treat each other differently and test each other differently, women are just learning this it seems.
