What EngineerSpeak is
EngineerSpeak provides AI-led mock technical interviews for software developers, data scientists, and machine learning engineers. It runs in a browser without requiring an additional software installation. Users can work through individual questions in learning mode or take a mock interview, answering aloud by voice. Feedback addresses correctness, completeness, missing concepts, answer depth, and trade-offs, while follow-up questions can probe assumptions, constraints, implementation, architecture, and production concerns.
Practice can be tailored to a supported role track and Junior, Middle, or Senior level. Optional English feedback covers grammar, clarity, professional vocabulary, and natural phrasing; the service recommends at least A2 proficiency for English interview practice. The homepage provides one free mock interview without requiring a credit card. Each pass includes an error report after every 15 questions. Audio is deleted after transcription, while signed-in users can review saved transcripts and feedback in their dashboard.
