Confluent - Interview Experience - Software Engineer Result: Offer Number of Rounds: 4 Phone screen was the variadic function library problem. Design a registry for function overloads, match signatures by argument types. Follow-ups on optional args and variadic flag. Felt manageable. Onsite had 4 rounds. First coding was tail -n: print the last N lines of a file using a given file API (read N bytes, move pointer, get file size). Tradeoffs between buffer approach and file pointer offset, with a s...

they gave the API: read N bytes, move pointer, get file size. you figured out the algorithm

random queue equality comparison is an interesting follow-up. same round as the implementation?

rohan.verma953d ago

same round. implementation, then equality, then thread safety. 60 min total
