Hi Leetcode, I have seen enough system design videos. I really wanted to get hang of a good system design interview book. I am in a bit of confusion regarding which to start with help me out choosing from The system design interview by Alex xu or The grokking design pdf that is pretty famous, since both of them have same format of explaining via examples.

I would appreciate to hear more from you guys, which books or source material helped you regarding the system design preparation. I am also going through Asli Engineering videos on youtube(Arpit bhiyani) and later plan to start book DESIGNING DATA INTENSIVE APPLICATIONS its a little heavy for starters.
