I'm Dhairya — a working data engineer who's been through the AI/ML and data interview grind, and came out the other side with offers. I remember prepping with no idea what to actually expect. So I put together what I wish I'd had: the questions that really get asked, the answers that land, and the traps that quietly cost people the offer. Everything here comes from real interviews and real work — not recycled theory from a decade ago.
