What you will learn

  1. How data engineering interviews are structured
    A data engineering interview isn't one exam. It's five or six different exams graded by different people on different things — and most rejections come from preparing for the wrong one.
  2. The SQL round: how to think out loud
    The SQL round isn't graded on the query. It's graded on the evidence the interviewer can write down — and they can only write down what you say.
  3. The Python round: what they're really testing
    A data engineering Python round is rarely about clever algorithms. It's a messy file, a dictionary and a question: will your code survive the 10 millionth line, the malformed one, and the next engineer who reads it?
  4. The system design round: a 6-step framework
    You already know the six steps. This lesson is about the clock, the rubric and the interviewer — because most design rounds are lost at minute 25, not at step 4.
  5. The behavioural round: STAR stories from your projects
    “Tell me about a time you disagreed with someone.” The interviewer doesn't want your opinion on disagreement. They want one real story, in two minutes, where they can see exactly what you did.
  6. Explaining your projects in 90 seconds
    “Walk me through your current project” is the question you'll be asked in almost every round — and the one candidates prepare least. Your 90-second answer decides what the next 30 minutes are about.
  7. Aptitude and estimation under pressure
    Aptitude tests aren't testing whether you can do maths. They're testing whether you can do enough maths, fast, while a timer runs — and whether you know when to skip.
  8. Salary, levels and the offer conversation
    An offer of ₹18 LPA does not mean ₹1.5 lakh a month in your account. It's closer to ₹1.1 lakh — and the gap is where most first negotiations go wrong.
