  1. Hi everyone! Just wanted to announce that we’ll be expanding our content and producing more videos every month. You’ll be getting videos that cover all aspects of data science from our team. Everyone on our team has industry experience so I know you’ll find the videos educational and interesting. Thanks for watching! And thanks for the support!

  2. The question clearly asks you to write a query (SQL). Solving it in a programming language makes it so much easier because of the additional constructs you can use.

  3. I nailed my sql technical questions (thanks to this channel), but they sprung a python one on me and I bombed it. Having so, so much trouble finding a job as a data science intern. Looking extremely bleak.

  4. Are we supposed to know these pandas functions by heart in the interview or we can look them up ?

  5. very clear explanantion. Thanks a lot😊.We expect more such awesome videos on Data science, please..

  6. Hey, nice video and informative
    Where can i find these type of questions in various difficulty ranges to practice..? Thanks in advance.

  7. I respect the work you put in your videos. I find it truly baffling that all major crypto you-tubers just look at pure wave and completely ignore the bigger narrative of why BTC is pumping and why the future outlook might not be as rosy as it seems. It's sort of irresponsible to ignore the fact that each ETF launch so far has caused a major dump at the peaks of BTC. We were already on shaky footing with historically low volume and almost pure whale pumps, narrowly avoiding a long-term bear market. this is the worst possible time in history to hodl as so many don't back up their crypto assets. more emphasis should be put into day trading as it is less affected by the unpredictable nature of the market. I have made over 9 btc with 2.7 btc from day trading with Daniel's help in few weeks, this is one of the best medium to backup your assets incase it goes bearish.You can reach Daniel on ͲeIєɠɾαm👉Danielwrightfx.
