I applied through a recruiter. The process took 2 weeks. I interviewed at Lilium (London, England) in Jun 2020
Interview
I found the whole process to be an enjoyable one.
At each stage (I had 6 remote face-to-face interviews), I was speaking with very smart and very interesting people and having some great discussions from very different perspectives. Everyone I spoke with was happy and able to confidently answer the questions I had for them and each of them asked interesting questions to me, which made for relaxed, conversational interviews.
The home test I received was great too. Very relevant to the company and wide enough that it allowed me to demonstrate my skills from a variety of perspectives.

Interview
After having a Zoom interview with a talent manager I've been asked to solve a take-home test. They provided a vague description of a booking system.
I was aware I didn't provide a production-grade level solution. As I pointed out in a README file, I focused on the domain correctness rather than scalability concerns like CQRS, etc.
Their feedback about my test was very arrogant and rude, also mainly contained comments about small issues, like not returning the proper HTTP status code or using an in-memory database rather than writing to a JSON file. I failed.
I believe a take-home test should be about the candidate's generic approach and getting familiar with their skills what you can continue discussing in the next round, like it works in a real team.
If you have a tech culture like this, I feel lucky dodging this bullet.
