Hello fellow LeetCoders,\n\nI have upcoming interview for SDE 1 role at Amazon. \nThey responded after the OA after almost a month and though I was happy that I cleared the OA at first, my interview is not getting scheduled and all I can do right now is study.\nAnyways, I had gone through several plans to cover all the topics and solve the general/relevant questions and I did so.\nBut now I\'m looking for an efficient way to revise DSA. I have solved over 200 questions, and have kept a list of questions which I thought are important, so I intend to revise them (50-70 questions). \nCan anyone suggest a better or more efficient strategy, or maybe a list of questions?\nAlso, can you suggest how in depth should I study Operating Systems for the interview?\n\nThank You
