Current Concept and IQ Generating Process 🔄

Currently, I follow a simple format to disseminate knowledge on Threads. I post concepts and interesting questions (IQs) as they come to my ENTP brain, which I have used in my professional journey and academia, have been asked in interviews, or that I could potentially ask in a data science interview. Once I have a question ready, I refine it to cover as many concepts as possible. Sometimes, I choose questions that are particularly thought-provoking to stimulate deeper discussions.
