What people say
"I used to freeze on 'tell me about yourself'. After three sessions I had a version I could actually say out loud. Got the offer."
Layla M.
Product Manager → fintech startup
"The resume tailoring is different. It doesn't puff you up. It just finds the real overlap and makes it visible. Hiring manager noticed."
James T.

"I did 8 practice interviews before my panel round. The actual thing felt like déjà vu. Easiest offer I've ever gotten."
