I applied online and got the reply in a week. There was an online test covering general questions in machine learning and coding. After that were several hangouts interviews asking about prior experience.
I went through two phases: (i) An online multiple choice quiz about data science, math, git & co, coding, deep learning, etc. and (ii) a google 30min hangouts interview with HR. In general, the application process was fast, transparent and nice. The interview was more about getting to know me, e.g., questions about my previous work experience, my goals, and so on.
Interview questions [1]
Question 1
What is the last deep learning publication you read?
Have you been involved in pair programming?
Why Luminovo?
What are highlights in your CV I should focus on?
I applied online. The process took 3 weeks. I interviewed at Luminovo (Munich, Bavaria) in Oct 2019
Interview
The interview process took 3 weeks. Firstly I got an email with an online test. You must answer 40 machine learning, deep learning and statistics questions in 45 minutes. Second interview was with HR and she asked me the meaning of a less known(nobody uses it like this) abbreviation. Also, while she was explaining the details of the company, she said that all the engineers are deep learning natives (it doesn't make sense!). If you are not graduated from one of top-level universities in the world, this interview can influence you about your education history because they are so proud of their educational histories.

Very nice and highly professional experience (best I've had). Well structured and organised, always letting you know what's happening next and providing fast feedback.
Process involved several stages, including an online test, hangout calls and on-site interviews.

Obviously mainly about ML and DL, some statistics and coding. Questions range from DL details to walking through a case study together.
