Hi HN,<p>I've spent my career continuously prepping and practicing for technical interviews, specifically SQL and python, and mainly for marketing analytics and some data science. I also teach SQL and python on the side and need a platform for my students to play around with.<p>I built Strata Scratch to help people prepare for their technical interviews and brush up on SQL and python. I loaded it with technical interview questions I've sourced from various sites. We created our own underlying datasets and changed the questions a bit keep original and test specific concepts that are often found on interviews.<p>The platform is MVP-ish, as it's only a side hustle but it's continuously improving. It's free to try out but has a monthly subscription if you want to unlock all the questions. Any feedback would be appreciated.<p>Here's a link to a Youtube we did also: <a href="https://www.youtube.com/watch?v=n6gM265zG68" rel="nofollow">https://www.youtube.com/watch?v=n6gM265zG68</a>
