What is Spark? Introduction to PySpark — Free Live Webinar | PrepNPlaced
Understand big data processing from zero — then write your first PySpark job, live. Durgesh Yadav · Sunday, 16 August at 7:30 PM IST. Free seat; notes included, recording optional.
Most people fail data engineering interviews for the same reason.
Not because they don't know Spark. Not because their SQL is weak. But because when the interviewer asks "how would you make this pipeline reliable?", they freeze.
The answer was never one clever trick. It's idempotency, retries, checkpointing, monitoring, and data quality checks. Say those five and you've already beaten most candidates.
I put together 20 pages of handwritten notes covering exactly what DE interviews actually test:
→ SQL that goes past joins (windows, dedup, running totals)
→ Data modeling: star schema, SCD Type 2, grain
→ Spark internals: shuffle, skew, narrow vs wide
→ Kafka, Airflow, file formats, system design
→ Behavioral + rapid-fire one-liners
No fluff. Just the questions that keep showing up, with answers you can actually reason through out loud.
Swipe through the carousel. Then grab the full set here: https://www.prepnplaced.com/prepnplaced-notes
One more thing 👇
Notes get you through the rounds. A real project gets you the callback.
That's why we're running a free webinar on building an End-to-End Data Engineering Project — the kind you can actually put on your resume and defend in an interview. Ingestion to warehouse to dashboard, the whole thing.
