Upsend is a tool designed to help users ace their software engineering interviews with autonomous mock coding interviews. The tool offers immediate personalized feedback to help users hone their coding skills and improve their interview performance. Upsend stands apart by fostering an interactive interview experience. Users can ask clarifying questions, discuss their ideas, and answer follow-up questions, mimicking a real-life interview scenario. The tool also allows for tracking of interview preparation progress by providing actionable insights and using industry-standard metrics on coding questions seen in actual interviews. It's designed to make the practice process less isolating by replicating the conditions and challenges of a real coding interview. The platform currently supports Python3 and C++, with plans to add more programming languages in the future. In addition, Upsend offers a frequently updated mock interview question bank to continuously challenge the users and keep them abreast with the latest questions. Despite being primarily focused on helping candidates prepare for coding interviews, it invariably aids in improving general coding abilities as well.
