  • This is a step by step guide for how I learned SQL for my FANG data science interview. I had never touched SQL before and only had 2 weeks to prepare for my interview. So I made a scientifically-backed study plan to learn SQL most efficiently with the least amount of time and effort. By the end of the 11 days, I felt super confident and prepared. I went on to pass my FANG data science interviews and got the job!
    My motto: Minimize effort and maximize outcome!!
    Btw apologies about audio quality from about 2 - 3.5 min mark. Something weird happened to my mic :(

    Hi Tina, thanks a lot for sharing your cool strategy for minimizing efforts and maximizing output! The 5 steps for solving SQL questions are great too - it helps to grasp the key information of the question, arrange our thoughts before writing queries, double-check to correct mistakes, make further improvement if necessary.

    Hi Tina,
    I am currently making the switch from HR Consultant to HR-Analist.
    Structuring the approach of a problem by writing down the query steps before you write and validate the actual query itself, wow!This was the key take away for me.
    Putting yourself through those steps first, not only shows you know what your doing for the interviewer. More importantly it helps and checks your implementational knowledge.
    Thanks for sharing this, this video just blew my mind :-)

    • @TinaHuang1
      @TinaHuang1  Před 3 lety +1

      YAY I’m so glad that resonated with you so much! That is one of the major things I tried to emphasize in the video. Took me a while to figure out tbh but once I forced myself to do it that way things started to click together. If you haven’t already I also highly recommend checking out a few videos in my sql Sundays series. I do interview questions in that style too and the questions are full real questions as opposed to this demo that was just a quick demo :)

    • @StudentOfLife-xf7ux

      If you max event_time_stamp and group by page_id, wouldn’t that that result in page counts for each of the current time stamp? We need the overall page counts if I am interpreting it correctly so maybe what you suggested should be the sub query then we count (*) from the sub query to get total pages on
