“Went with DFS, marked visited cells in-place by flipping 1s to 0s.”
“I started with the basics, POST request, credentials in the body, server validates against a hashed password in the DB, returns a token.”
“I went with a distributed data pipeline I'd built, which felt like the right call, but I rambled way too much about the architecture and not enough about my actual decisions and tradeoffs.”
