I have been routinely questioned about what happens from when you type www.somesite.com and when the webpage is displayed when interviewing over the years and realised that nowadays I could fill 2 whole hours talking about all the stuff that actually happens (and many times I would have to say “but about this specific thing I’m not very knowledgeable about)… whereas at the start of my career i would have probably spoken for like 15 seconds and felt smart about answering “such an easy question”.
