Llds question asked at Amazon for Sde 2 interview

I have Amazon Sde 2 interview coming in 9 days. My leetcode is fine and system design is okay. But I have not yet practise LLDs much. Can anyone suggest me some problems or resource I can go through for it. Any most frequent problems asked at Amazon? I know design parking system, LRU cache are asked a lot. Also any resource for system design. I have gone throigh Alexa xu and Gaurav Sen video only. #engineering #software #swe #amazonaws #amazonsde2 #amazoninterview
