Any more detail on the system design round? Feels like the vaguest part of their whole loop from what I've seen mentioned.

Did the mid-day cut freak you out? Sitting through lunch not knowing if you're getting the afternoon rounds sounds brutal.

Ngl it was rough, I just tried to eat and not think about it too much. They told us pretty quick after lunch started so at least it wasn't a long wait.

How was the continuous time follow up on the watcher problem? That one always seems like it'd be a nightmare to explain out loud.

I got a version of this too on my phone screen, the segmenting by reversal timestamps thing took me a solid ten minutes just to wrap my head around.

Congrats! I had the same buffer parser type OA a while back, felt way more like a systems class exam than an algo test lol.
