What it does
interviewing.io offers anonymous technical mock interviews and coaching for software engineers. Its subject areas include coding, system design, machine learning and engineering management, with a free AI interviewer and separately priced human sessions.
Choose the subject and level of the practice before booking. A coding session and a staff-level system-design discussion test different skills, and the service provides several specialisms and coaching formats. Human sessions use audio, chat and a shared coding environment without video, with an option to reveal identity afterwards.
Feedback is part of the mock-interview workflow, giving material to use in the next practice session. The FAQ states that premium interviews start at $179 and vary with subject and interviewer requirements. The AI interviewer provides a free route for coding and system-design practice before paying for a person’s time. Compare the session format with the interview you expect, while keeping mock practice separate from an employer’s actual assessment.
