Most interview prep is polite. Real panels aren't. AISIM puts you in a voice conversation with AI personas that interrupt rambles, challenge vague answers and follow up until you get specific — then score you on structure, evidence, follow-ups and concision. 15+ rooms: PM, engineering, sales and data loops, SBI/IBPS/RBI and UPSC boards, US visa windows — or paste a job description and get a custom panel. Warm-up, Realistic, Nightmare. Practice-only, never live assistance.
