Offer Letter is a web-based interview preparation tool built around a simple idea: the best way to get better at interviewing is to actually interview, over and over. Instead of reading static question lists, users sit down with an AI interviewer that poses behavioral and technical questions and lets them practice answering out loud. The platform highlights Product Management case studies as one of its core exercise types, alongside general behavioral and technical question sets.
The product is aimed at candidates across several fields and functions, including product management, finance, consulting, and technology roles. Because practice is self-serve and runs in the browser, users can run a session whenever it suits them rather than waiting for a human mock-interview partner. The site presents itself as a new AI-powered platform and keeps a very lightweight footprint, with a contact address for questions and feedback.
Functionally, Offer Letter sits in the growing category of AI interview assistants and AI coaching tools. Its value is repetition and structure: candidates can work through categories of questions, get comfortable with the rhythm and pressure of a live interview, and refine how they frame their answers. Anyone evaluating the tool should treat it as a practice aid rather than a guarantee of outcomes, and should check the current site directly for the latest feature and pricing details.
