I applied through an employee referral. The process took 1 week.

phone call with HR, then an interview with two managers. They were nice, nothing special about the interaction, I spoke about my experience and specific project I want to go deeper and I went a little deeper. Really interested in data, probably the role was more data oriented, they asked a lot about SQL. Also about deployment, what happens in deployment, Then one exercise about dictionary, and how it works internally. Then they asked me to implement one

You need to implement a dict in O(1).
