Hello :) Today is Day 331!
A quick summary of today:
- watching more of the pre-recorded content on dataexpert.io
- doing more SQL exercises
Spark + analytical partterns content
Today I covered lectures + labs on the above two topics. As always, I cannot share my notes or anything related as it’s content 100% behind the wall on dataexpert.io.
More SQL practice
After finishing the SQL practice Qs on the dataexpert platform yesterday, I started looking for other websites with SQL practice questions. I considered the obvious ones - hackerrank and datacamp. But then I asked a person who I know works as a DE and is experienced with SQL about their opinion on a good website (the person is George from the Zach Wilson community server). George suggested interviewquery so I signed up for a month (using the blackfriday discount 😆) and started from easy to hard Qs again.
Today I solved:
(somehow I set my weekly goal as 25 questions 😆)
21 Qs. I was always selecting next Q after finishing one and somehow I solved a medium Q but I checked and there are like 40 more easy Qs (60 in total), and then I will move into Medium (which seem to be the most) and finally Hard.
That is all for today!
See you tomorrow :)
