It's a very large French bank. I don't know anything except that it was a paired batch processing server and didn't push further questions, honestly. For some reason, I found absolutely nothing in the news about it, but my source of information is credible. It doesn't surprise me for a second that it happened, since, for example, I spent months trying to get these guys to fix their literally useless MQ DR failover scripts, but nothing ever came from it, since, they didn't have anywhere to test.
With the way they treat their employees - fucking good riddance. There was a giant mess when Disney forced their NOC to train their replacements, but yet these guys did the exact same thing, plus some, and there was no public awareness during or after it. The best part was their push to move everyone to Montreal. Lower pay, not a guaranteed extension and you're forced to move? Okay.
The AMRS CTO actually left about a month after he got the position and took me along with one other person over to a new company. Goldman's head of tech actually just left to go to the same place. Not gonna lie, it sounds incredibly suspicious, especially considering the the kinds of shenanigans that went on there... thankfully I'm no longer working there.
