typical first round -> situation around the question not just a lc -> string parsing -> asked runtime qs as well -> interviewer was very chill & nice; encouraged me + pointed in right direction

My interview process started positively, with a smooth recruiter experience and engaging initial technical rounds. However, the final technical interview did not meet my expectations. I began the interview by asking clarifying questions about the coding problem to ensure I fully understood the requirements. Unfortunately, the interaction became challenging as my approach to solving the problem was not well-received. I proposed solutions, including using a ListNode in combination with a dictionary to implement the LRU Cache, and even suggested using an ordered dictionary. However, my ideas were dismissed without much discussion or collaboration. I attempted to pivot to a dictionary-based solution but was informed that the interview would end early as the discussion was not progressing effectively. This abrupt conclusion left me feeling the interaction lacked professionalism and a supportive tone, which I hoped for from a senior-level technical interview.
