Most AI interview tools accept whatever you say and move on. Tail Villain doesn't. Like a real interviewer, it digs into your answers with sharp follow-up questions until your weak spots show. Practice by voice or text, get feedback on every answer, and follow a personalized roadmap for your goal — job interviews, coding interviews, language exams like IELTS, or certifications like AWS. Stop rehearsing scripts; start handling the questions that come after them.
