I applied online. The process took one week.

Nubank's interview process was excellent from start to finish. They are clearly hiring senior-level specialists, so the technical challenges were hard but fair. I appreciated the recruiter team's proactive communication, with timely emails explaining each step, and felt supported throughout. I highly recommend it!

They asked me to walk through a real-world Spark use case I'd implemented—building a streaming ETL for clickstream data—detailing how I managed stateful windowed aggregations, tuned spark.sql.shuffle.partitions, and fixed data skew with a custom partitioner.
