Behavioral Technical Coding
The process is pretty thorough, it goes like this: first you have a call with HR. Then you chat with the manager of your team, who asks some technical stuff but it's not a full technical interview. After that, there's a technical test to do at home where you have to build a simple data pipeline. Then, you debrief your work on the test with two data engineers who will challenge what you did. Finally, there's a call with the head of data, which seems more about cultural fit, though I didn't make it that far.
Confirmed questions2 questions
