Hi Leetcode community,\n\nI have recently completed OA for SDE (Amazon Seattle). A recruiter has reached out to me and discussed that he was going to sent a online assessment. He is so professional, he has called me directly and spoke for like 15 mins and given few tips on how to prepare for the OA. He has sent the OA and mentioned that the link expires in 14 days.\n\nOA Questions:\n\nNumber of Islands (Changed to number of parking lots):\n\nhttps://leetcode.com/problems/number-of-islands/\n\nRe-order the log file:\n\nhttps://leetcode.com/problems/reorder-data-in-log-files/\n\nI have completed the test in like an hour(All the test cases passed) and added comments to every part of the code for rest of the time. (Make sure that you do this, many people will ignore this but, this will be mentioned in mail he sends you). Recently, I have got an invite for virtual onsite interview.\n\nI have asked many of friends who also got an OA invite from Amazon, I have found all the questions are almost the same they include.\n\nK - frequent words (Asked as top K reviews)\nNumber of Islands (Asked as number of parking lots)\nCritical Router (very similar to critical connections)\n\nThey have said that all of them are able to complete one question(run all the test case) and partially did the second one (Only few of the test cases got tested). So, they have been invited to a phone call interview prior to onsite interview. So, inorder to directly get call for onsite interview you need to complete both the questions.\n\nHope this will help!
