Given a DAG of dependencies, how do you order execution correctly?

"The process was well organized and the interviewers were collaborative. I did well when thinking aloud and adapting to new information. I could have managed time better during the unfamiliar-codebase round."

"This process took forever. It was roughly six weeks of interviewing after they reached out to begin the process 6+ months after I had applied. They skipped the recruiter screen and put me straight into a hiring manager technical screen, then a virtual onsite with five rounds in one day. Almost everything was technical, and the two hardest parts were the systems design round and the domain-specific PyTorch / distributed training deep dive because they went really deep. The communication was kind of rough and I did not learn much about Nvidia's broader engineering culture, but the actual interview quality was quite good and the engineers felt very competent and very clear on what they wanted for the role. The weirdest signal to me was the final 'intellectual honesty' round, which made me think this team may have gotten burned on a previous hire and was being extra careful."
