After phone screen with HR, got a phone interview with an algorithm question for an hour, then went on to on-site. I got the expected format of 2 engineering interviews with 2 questions each. First interview were Leetcode medium questions related to Candy Crush and condensing a LinkedList. Second interviewer gave me a variation of the Knapsack NP-Hard problem but complained about my run-time being exponential. He didn't even know what the Knapsack problem was. Not surprisingly, he walked me out of the office and I didn't get the offer.

Overall, it was a positive and professional interview experience, though the interviewer was on the stricter side. Unfortunately, I was dealing with an illness and wasn't able to prepare as thoroughly as I wanted to, which left me feeling a bit off throughout the conversation. Despite not feeling my best and facing a tough interviewer, the process was well-structured.
