Jeff Dean, MapReduce Inventor, Asks 'What Is DSA Hard?'

Description

A screenshot of a Twitter/X thread in dark mode. Jeff Dean (verified, @JeffDean) explains the origin of MapReduce: while rewriting Google's search indexing pipeline, the team realized many phases were 'conceptually simple but required large scale processing (extract link text from each page, identify language for...' with a 'Show more' link; the tweet shows 13 replies, 44 retweets, 946 likes, 41K views. Vishnu Vivekanand (@vishnuvivek87) replies: 'Genuine question, Jeff. How much of DSA hard (to be solved in under 15 mins) help you build this?' Jeff Dean responds simply: 'What is DSA hard?' The humor lies in the legendary Google engineer who built planet-scale systems being completely unfamiliar with leetcode-style interview jargon, exposing the disconnect between competitive interview prep culture and actual systems engineering

    He mapped the web and reduced petabytes; naturally, the next benchmark is reversing a linked list in fifteen minutes.

    What

  4. @imDaniX 2mo

    But fr, what is DSA and why's it hard?

  5. @deadgnom32 2mo

    What is DSA hard?

  6. @Similacrest 2mo

    Everybody asks "What is DSA Hard?", nobody ever asks "Who got DSA hard?"

  7. @lb_ii 2mo

    What is DSA Hard?

  8. @MANGIAMONDI3000 2mo

    do you have a DSA hard in your pants or are you just happy to see me?

  9. @SwedishSock 2mo

    Dsa stands for data structure and algorithms right? Isn't that just what all programming is?

    so it is leetcode-speak

  12. @Sun_Serega 2mo

    apparently there is some data struct and alg lvl with "Hard" difficulty and that have to be solved under 15 min

  13. @TheUnknown007 2mo

    You get taken out by the leetcode strike team

  14. @Sun_Serega 2mo

    idk don't ask me. the concept of retriable task with time limit baffles me too, but so does the rest of the leetcode, and they somehow still in business

  15. @Agent1378 2mo

    Thats a nice sarcasm. 2nd guy probably references standart hiring tests, which for google included math, dsa etc. etc.

  16. @b7sum 2mo

    a daily reminder to keep grinding your leetcodes
