May 2026

Summary

Speak's software engineering loop covered three distinct angles: product thinking, team dynamics, and a technical deep dive into a past project. It felt more like a PM/EM hybrid than a typical SWE interview, which I wasn't fully prepared for.

Questions Asked (9)

Q1

Pick a user problem in the speaking practice space, define who the target users are and what job they're trying to get done, and walk through the key use cases you'd focus on.
