Practise the interview for the job you want, and hear where you undersell yourself.
Paste a job description. An interviewer asks you five questions for that role. Answer out loud or type. Then you see how much of what you said came across as junior or senior, the habits behind it, and a rewrite you could actually say.
This is an editor for trained habits, not a confidence test. Warmth, questions and credit to others are not weaknesses, and it won't treat them as such.
Free, no sign-in, nothing saved. A made-up candidate answers; you click through and see her results.

Speak it with "Record my answer", or type. After recording you can fix words the transcription got wrong, but leave your ums and likes in: they're part of your score.
