In today’s competitive job market, preparing effectively for interviews is crucial to standing out and landing your dream job. Artificial Intelligence (AI) has revolutionized interview preparation by offering personalized, interactive, and insightful practice sessions that simulate real-world interviews. However, most AI tools for job interview preparation are not truly free—even those that claim to be. Many offer only a limited number of questions or restrict access to key features in their free versions. In fact, a significant number of AI interview tools do not provide any free trial or meaningful free access at all.

Importantly, this list only includes tools that offer a free plan or a trial option, letting you test their features before making any commitment.

Best of all, these platforms let you practice anytime, anywhere, often with no credit card required.
