Think of this as your safety net — while the daily cards train your interview thinking.
How the Survival System Works
1 Interview Question
One real Data Engineer interview question per day. No theory.
What Interviewer Expects
Plain-language explanation of what the interviewer is listening for.
The Trap Answer
The common answer that sounds correct — but gets candidates rejected.
10-Minute Thinking Task
Small mental exercise so the answer stays in your head.
Example – What you receive daily
Interview Question
How does Spark handle data skew?
What interviewer wants
Do you understand why skew breaks parallelism and how Spark actually reacts?
Trap answer
“Increase partitions” — shows shallow understanding.
Thinking task
Explain skew handling without using the word “partition”.
Task Answer (Simple & Interview-Safe)
Answer 1:
Data skew happens when a small number of values get most of the data. Because of this, some Spark tasks run very slow while others finish early.
Answer 2:
Spark struggles because work is not evenly distributed. The solution is to handle heavy keys separately or spread the data better, not just increase partitions.

One failed interview costs months of time and confidence.
