“I've built React apps before, plenty of them, but muscle memory is a real thing and mine had completely atrophied.”
“Answered it straight, picked something real but minor, and they came back with 'why did you do that?' and then 'is this a pattern for you?' Felt like a trap I walked into by being honest.”
“I froze.”
“Said ping and traceroute and immediately regretted it.”
“This is the thing I keep going back and forth on.”
“I paused for maybe two seconds to think and the guy repeated it back at me like I was an idiot.”
“This is where I fell apart.”
“I actually walked through the whole thing line by line, explained what each section was doing, even predicted the output.”
“My brain just stopped.”
“This is the one I'd like to forget.”
