But this is exactly why it's standard procedure. I worked for a huge Credit Reference Agency and it was very obvious that this is ass covering.
Sarah and Bob in the New York Office of Huge Corp must take the training so that the CEO can swear all his employees know not to bribe people. In the event that Manuel, who is given $100 000 per week of company money to bribe the locals in Melonistan so that they don't interfere with Huge Corp's operations is actually brought before the government and forced to spill the beans the CEO will insist they had no idea and some Huge Corp minion gets sacrificed. Manuel will be replaced, Melonistan will be assured quietly that his replacement will provide make up money ASAP.
In Arms this is even worse, because there it's secretly government policy to bribe people, even though it's also illegal. So then sometimes even if you can prove there was a crime, the government will say "We'll take that evidence thank you very much" and poof, the crime disappears, if you make too much fuss you'll be made to disappear too.
Not just onboarding. Most, if not all, large companies waste at least an hour of their employees time on this per year, while themselves bribing politicians in DC.
