OMG I owe me pushing my career to the next level due to Pavlo's course! There's so many technical interviews where I've impressed my interviewer with explaining low-level details of how databases do things. Don't be fooled by the course name though, it's pretty rigorous but so rewarding and practical (especially if you are a data engineer). I give this course an A+ for teaching me about B+ trees in C++ :D
