Here are three stats about how your money is increasingly useless after the most recent inflation report
I have an upcoming tech screen for the upcoming interview with Datadog. I've been leetcoding a lot, especially the top interview questions and so on, but if you can share any examples problems that are usually asked there I'll be very grateful. Likewise, what is the usual approach of their system design interviews? I'd like to prepare and practice for these, but I'm not sure on what to expect.
I had my phone screen last week. I had two LC easy questions: one arrays question and the other was a tree question. I struggled just a tad but totally completed both in the time allotted, but they still failed me. I think their bar is higher than Amazon’s at least for the phone screen stage.
Do you remember the questions by any chance?
Nope, sorry! They weren’t super weird questions or anything, though.
Your recruiter should be able to provide you with a prep document that goes into detail about each interview and how to prep for each of them. If they have not provided you with them, please ask them.
Mine specifically mentioned LC mediums
From my research a year ago on the company, these are the topics I think are most relevant to them but I of course may be wrong/outdated. However if you had to gamble on very specific topics these are the ones (IMHO) that will give you the best chance. Prepare for String Matching, Inverted Index, Tree Traversal and (less frequent) OOP design problems. All won't exceed Medium level. As for system design, main problems should be Youtube/Netflix or Distributed Logging styles.
