Empyrean Benefit Solutions Frontend Engineer interview questions

The interview process began with an initial HR pre-screen, followed by a panel interview with the frontend manager and a senior frontend developer. After these initial stages, a technical coding challenge was issued. This challenge was quite extensive, requiring approximately ten days to complete a comprehensive web application and accompanying presentation. I was explicitly told I would present and discuss this work in the next interview round and, if I was successful there, the final interview would be with the VP of engineering. However, despite the significant effort invested, the coding challenge was never reviewed. In my next interview, I did not meet with other developers, instead I met with a VP (Jason), and in that meeting, there was no discussion or even acknowledgment of the code or presentation I submitted. When I proactively offered to discuss it, the VP seemed unfamiliar with the challenge's existence. The questions asked were general and backend-focused, completely disconnected from the frontend role and the prior technical assessment. This felt like a significant disregard for the time and effort I put into the required assignment. I had prepared to go into a code review, but was then asked definitions out of a text book. I understand why they did not offer me the role as I did not answer these questions very well (at all). Following the final interview, I received a standard rejection notice (I was not surprised). When I later sent a detailed email providing constructive feedback on the interview process, specifically highlighting the unreviewed coding challenge, the response I received was a generic, boilerplate email, almost identical to the initial rejection notice. This further compounded the disappointment and inconsistency felt throughout the process.
