What EngineerSpeak is

EngineerSpeak offers browser-based AI mock technical interviews for software developers, data scientists, and machine learning engineers. Users can work through individual questions in learning mode or practice in mock interview mode, answering aloud by voice. Feedback addresses correctness, completeness, missing concepts, answer depth, and trade-offs; follow-up questions can probe assumptions, constraints, implementation details, architecture, and production concerns. Practice can be set to supported role tracks and Junior, Middle, or Senior levels. Optional English feedback covers grammar, clarity, professional vocabulary, and natural phrasing, with at least A2 proficiency recommended for English interview practice. The homepage provides one free mock interview session without requiring a credit card. Paid passes are one-time purchases with validity periods: Interview Sprint costs 11.50 USD once for 30 days, Job Hunter costs 20.00 USD once for 75 days, and Interview Killer costs 38.00 USD once for 180 days. Each pass includes an error report after every 15 questions. Signed-in users can review saved transcripts and feedback in their dashboard. Audio recordings are deleted after transcription and are not retained.
