“This is the one that probably cost me the offer.”
“Two of my four interviews were HR reps who straight up told me they had never interviewed for a CS role before.”
“This came up constantly across multiple companies, basically a deep dive into something real I'd built.”
“Spent the first few minutes just trying to nail down requirements because this thing could go a hundred directions.”
“Big open-ended prompt.”
“I actually got through most of it.”
“This is probably where I tanked it.”
“My first instinct was a simple incrementing counter and i ran with it for a bit before they nudged me toward deallocation.”
“The question itself wasn't crazy hard but the vibe in the room made it harder than it needed to be.”
“I started with naive repeated addition and they immediately asked me what the complexity was.”
