Alex! Thanks so much for reviewing our platform! I'm glad you found the platform helpful and I hope others do too. As you mentioned there are 50+ questions that are free. We also try to release in-depth data science articles almost daily...which are also free! So hopefully there's something for everyone.

Love your channel. It's been amazing seeing your channel grow from what it was a few years ago to what it is now.

I am right now looking for an internship and you could not have done a better video for me !! Im also following you since few months and your content is such a gold mine for Master and Msc students getting ready to jump into the business. Thank you very much Alex !

Could have really used this a few weeks back before I finally got an internship 😅😅 would have saved me so much time. Still gonna be useful for the future tho 🤓

Great shout-out Alex! Nate from Stratascratch really deserves it! I've been using his website and also watching videos from his youtube channel sharing hist approach to solve some of the questions, that help me improve my skills in SQL and prepare to technical interviews.

I have a tech inteview with a SQL assessment tomorrow, perfect timing. Been using leetcode but I'll check this out too. Thanks for this Alex

(Longer comment, because this is so relevant to me right now both as an instructional designer who's added data analysis to the mix:)
After having my first couple of technical interviews, this is invaluable @Alex. Candidly, this is a completely different world from an artificial environment such as a DataCamp or other fill-in-the-blank approach. Filling in blanks does not teach our brains to demonstrate the real-world competency that our future team is depending on from us :)

In learning engineering lingo, we call this disconnect the difference between the "learning context" vs. the real-world "performance context". The goal of solid training is to first teach the basics but ensure that learners demonstrate mastery (whether basic or advanced) in a real world context. In the case of those of us who want jobs in this field it will be necessary to communicate what is going on in our brains just as you do in this video. To be super transparent with you and others reading this... In my first such interview I candidly felt like a 2nd grader learning phonics and sounding out words... which was an unpleasant feeling to put it mildly.

Having to "talk through" a completely new SQL problem in real-time is very much a performance, and having a way to simulate this in real-time would be helpful.
You demonstrated this competency in this video, and that helps to a significant degree. Some sort of service or "fishbowl" style masterclass could also accomplish this.

The "community answers" feature in StrataScratch is new and very helpful as there is more than one solution to these issues. Live "Fishbowl" style webinars (one person answers while others observe) or even asynchronous video submissions which could be reviewed within 72 hours or whenever could provide invaluable feedback in addition to forcing us to go through the real life situation that most job seekers will face.

Check out Nate's channel, as well: he explains the queries very well. Glad to see this collab.

Hello Alex, you are just the best. Your videos are really timely for me. Help when I need it. Watching this now.

[jerrisg]

This channel is becoming above and beyond many others. Good work.

The preview feature is superrrr useful for me. I used to practise MySQL in HackerRank, LeetCode, and InterviewQuery, three of them don't have a preview and run the code to check the result.

[ekpotgodswill]

This is amazing Alex, thanks for this🙏.

[krishnabarfiwala]

The perfect video I could have asked for ever 😁😁😁

[raynaldy]

Noooo, I just did a technical interview yesterday and I'm far beyond prepared 😂

[NotFound-iuwx]

I watch Nate's video too. Very useful

[relax]

I joined this morning and was able to do most of the easy ones.

[drtruma]

Great Video! I’m glad I’m not the only person that thinks leetcode is exceptionally difficult lol.

[jaberabedin]

Awesome stuff Alex - would you say being comfortable with medium-difficulty StrataSratch SQL questions is the bare minimum requirement (for the SQL portion) to be qualified to apply for data analyst jobs?

[shrutikaaggarwal]

Could you make a video on one of the interview question "What is your salary expectation?"

[sabasjee]

Hello Alex, First time i watched this video someone recommended me.
i have couple of questions please.
My first question is, I applied many places but didn't get chance to call for interview i don't know the reason.

And any website you recommend me for perfect practice SQL? Beginner to Master
What kind of question they asked during interview for data analysis?
Thanks

Hi Alex, I have a request for a video please do a review on the WGU masters in data analytics
