I applied through a recruiter. The process took 2 months. I interviewed at Databricks in Jan 2020
Interview
I was contacted by a talent acquisition manager for a Data scientist role. I passed 7 interviews and one technical and a coding assignment. After that, I was ghosted by the recruiter, no mails no calls. I reached out to them and they said they are having a couple of meeting to shape of the team moving forward and where they need the right skillset. So they asked me to wait and then I got ghosted once more. In the end, the manager told me that they have no needs in Paris. So after 2 months of interviews and preparation, they managed my candidature in a cold way.
I'm really disappointed at the way they handle the process and I hope they upper their game to match with a big company as Databricks.
The interview questions includes from ML concepts to python design, which is harder than I expected. But can use SQL as well. You can choose what you want to use.
3 rounds, 1 case interview, 1 fundamentals and 1 SQL interview. The case interview was extremely technical and the fundamentals interview didn't cover my resume at all. Overall it was quite difficult, and the fundamentals interview prep sheet was not helpful at all
