ADCI - Karnataka Software Engineer Interview Experience: rain fill, LRU, and delivery-service design

My interview focused on a couple of familiar technical questions. One was a straightforward "fill rain" problem. The design portion came afterward. One prompt felt close to an LRU cache, and the higher-level task was to design a delivery service similar to Uber or DoorDash.

The conversation was practical. I reasoned through the core logic first, then moved into system-level thinking for the design discussion. It wasn't overly adversarial, and the questions followed common patterns.

I received an offer. My impression was that they weren't trying to catch me with trick questions. They wanted to see whether I could turn familiar patterns into a coherent approach.

Location: New York, NY. Overall feedback: positive. Offer status: got offer.
