This doesn't sound like a useful service. Problems that people have with interviewing on the phone are not that they can't hear the question that's being asked. They mostly stem from the fact that interaction space with the interviewer is so much more limited.

Your service does not simulate a phone interview -- there's no ability for your automated service to interpret and judge responses and to provide feedback.

I suggest you pivot into setting up mock interviews between developers. They can interview each other getting valuable practice and then rate each other on interview skills on both sides of the fence; your value is in - setting up developers with each other and tracking their info/scores if they do more than one interview - providing interview scripts and questions to guide them

You are right. Since its an automated system, you can't get follow up questions. You can only practice by replying to a script. I believe this is the biggest drawback with my approach. I was thinking of it as a way to build your confidence by actually hearing yourself on the phone after the interview.

I like the idea of having developers interview each other. Thanks!
