Question 1

What behavioral questions are asked in data engineering interviews?

Accepted Answer

Common behavioral questions include: Tell me about a time you dealt with data quality issues, describe a project where you had to optimize a slow pipeline, how do you handle conflicting priorities from multiple stakeholders, and tell me about a technical decision you later regretted.

Question 2

How should I prepare for behavioral rounds as a data engineer?
