This feature is aiming to truly simulate the interview experience, being the flagship of our business. Here, if you do not know the complete answer to the question straight away, the marker won't directly grade you (like it happens in regular Premium), instead, you will receive guidance and questions that will lead you towards the answer that the interviewer wants to hear. Long story short, this is a mini conversation (of maximum 3 attempts back and forth) between you and the interviewer, where you both work towards solving the problem. This is not just using a wrapper around an LLM, the language model always refers to the golden answer from our proprietary database to really have the full context and act like an interviewer. This experience cannot be replicated on the ChatGPT website.

Coding questions are evaluated exclusively using unit tests tailored for each problem, while quizzes are graded by comparing your answers to the correct solutions. Our 'Questions' section evaluates submissions using our own proprietary ML-powered essay marking system. This system carefully compares your answers to our hand-crafted, trusted ideal responses from our database focusing on the key concepts that interviewers look for, providing accurate and meaningful assessments.

This website was built out of passion for interview assessment and helping people land their desired job. All interview question answers on our platform are expertly crafted by our two technical cofounders. With advanced degrees in AI from renowned universities and over 8 years of combined industry experience, they've developed large-scale ML systems and recommendation engines serving millions of users at leading tech companies. Their research contributions have garnered over 80 citations. Their skill set encompasses a broad range of technologies and methodologies, including Python, PyTorch, AWS, GCP, MLOps, distributed computing, and quantitative finance. One of our cofounders is a Lead Machine Learning Engineer who has interviewed over 100 candidates throughout his career, driven by a deep passion for interview assessment and a commitment to excellence.

We believe we have constructed the most comprehensive and complete list of interview questions in the data and ML space that there is to date. This is what powers our platform. We have sourced questions from open platforms such as Glassdoor, Blind, Quora, Stack Exchanges, YouTube, as well as from both our own writings and public blogs, among many other reputable sources. Every question on our platform has been used in real interviews. While some theoretical questions, like 'What is the bias variance tradeoff?' are so fundamental that specific sources may not always be identifiable, they remain essential components of data and machine learning interviews. Regarding coding questions, we understand that machine learning interviews often involve take home assignments rather than live coding sessions. As a result, not all coding questions on our platform originate from actual interviews. Instead, we have adapted shorter coding challenges to resemble the unique machine learning coding problems commonly encountered in the industry that are not typically found on platforms like leetcode.
