The overall experience was disheartening, especially considering the time and effort invested.

The recruitment team was very unprofessional and lacked experience working with senior-level candidates.

The interview phases, which comprised one architectural discussion and two coding sessions, were fairly standard. Feedback post-interviews was positive.

However, there was a significant disconnect when it came to compensation. The offered salary was a surprising 40% below my previously stated expectations, which were clearly communicated beforehand. No clear answer regarding this difference was given, and no official email was sent. Primarily, all communication was done through informal Telegram calls.
