One thing they WILL test if you're lucky to make it to interview is your ability to stick rigidly to the safety rules, so if it says 60 they mean 60 and not 61 lolComing from a background with a ton of rules and policies around security, etc. I do understand the inflexibility of it being dead-on 60 minutes. As gutting as it is to be 5 minutes out! It's just the 90 minutes bit that rubbed me up the wrong way - as an outsider/layman to the rail industry I was really looking forward to it as a new long-term venture. A lot of my previous role would have meshed perfectly with their requirements. Not to mention the wacking-great pay to go with it. Anyway that's just me whinging.
But you're right, they're only human. If the rules say 60, then, 60 it is.
