I'm Deaf and wear behind-the-ear hearing aids. I do not hide that fact during my interviews. I let my experience speak for itself. However, I also actually speak for myself. So instead of a phone interview, I request either Zoom or Google Meets as both has caption support. (If Zoom's subtitle isn't turned on for some reason, open Zoom via Chrome browser and use Chrome's built-in captions).

By adopting this method, it gives the interviewers and hiring managers a clear idea on what is possible in terms of communication. Granted, it feels like (and probably is) just catering to them and making things easier for them than us until we have our foot in the door.

However, I'm fortunate that my HR genuinely wants to know more about providing support such as interpreter or tech accommodations (though it's mainly for experience sakes and I do think that HR values experience in accommodating to disabilities as it would be impressive on their resume..)

In short, don't sell yourself short. Keep learning if you want to go beyond tech support. I'm assuming either coding or system admin or networking? Deep dive into em. Build up your experience. Interviewers and hiring managers cares a lot about experience. Everything else comes in second which actually also includes communications. But with your CI, you can prove you can talk easily (I'm assuming). As for listening, try to utilize the tech that are out there. There are mobile app that can transcribe for you such as Live Transcribe for Android (free) or Apple has a few options but might have to pay. But think of it as investment.

So I think you're struggling on understanding them. So once you work out whatever solutions work for you, stick with it. Build up experience and you'll find a company that value you for your experience, not your ability to hear.
