About

Gadfly is a voice tutor for technical interview practice. You work through algorithms, system design and behavioral rounds out loud; the tutor answers with questions. It names what broke, remembers the weakness and brings it back until it clears. It quotes your words and the minute when it can, and says nothing if the record is too thin. For engineers facing big-tech interviews. 2 free sessions, no card. Laptop or desktop, Chrome or Edge. Built for preparation, never live-interview assistance.

AI Summary

A source that found nothing is a measurement. A source that has not run is a gap. Neither means the launch lacks the thing.
