Not hard, but a bit long. They used to have 4-5 rounds but now 3 rounds. Candidates should be familiar with their experience and projects. People are nice to talk to.
Interview questions [1]
Question 1
Dig into the machine learning tech of past projects.
I applied online. The process took 5 weeks. I interviewed at Jina AI (Berlin) in Dec 2022
Interview
The interviewer asked some questions about Python basics and also a leetcode easy question. We also discuss about the difference between Python and C++ (going through some specific features in C++, like smart pointers). The interviewers are professional and very friendly. Nice experience.
I joined very early, so I interviewed with almost everyone on the team, it's very different now tho.
Now we have some HR screening, then coding tests and then calls with CEO

I don't remember the coding questions, but the other ones were very theoretical about Python.
