“This one is deceptively wide.”
“I jumped straight into writing the individual functions before thinking about the interface, which was the wrong move.”
“This is where I spent most of the interview.”
“Standard opener but I rambled a bit.”
“This is a build-on-top problem, so if your Level 1 was messy you'll feel it immediately.”
“Blanked for a second because I expected something more strategic first.”
“This started as a trie question and turned into basically a systems design conversation about string indexing.”
“Time was tight and I wasn't moving fast enough, the interviewer had to nudge me along a couple times which was a little embarrassing.”
“This one threw me a little.”
“I got the happy path working fast and felt good about it, then they started asking about ties.”
