  • “System design interview for data engineer roles at a Toronto fintech”

    I'm looking for a mock system design interview for data engineer roles at fintechs in Toronto. I have four years as a data engineer at a telecom, working with Spark, Airflow, Kafka and Snowflake. The next round at a fintech is a 60-minute data system design: a pipeline for real-time transaction events feeding fraud models and daily reporting.

    I'm solid on batch but less confident on streaming, late data, schema changes and data quality checks. I'd like one 60-minute mock on a similar problem with written feedback, plus 15 minutes of questions after. Please mention your data platform experience in your offer.

  • 01

    How much does coding and system-design interview cost in Canada?

    Usually C$50–250. Each Tasker names their own price in their offer, so you see the cost before you agree to anything.

  • 02

    Event time versus processing time, watermarks and late data, exactly-once delivery, partitioning keys, replay and backfills, and how downstream tables stay consistent.

  • 03

    How should I start a data pipeline design question?

    Clarify consumers and freshness first: who reads the data, how fresh it must be and what happens if it's wrong. That decides streaming versus batch.
