The process was fast, after 5 interviews they just ghosted me although they seemed to be happy with all interviews, some weird vibes from one of the founders, the rest of the interviewees were friendly
I applied through other source. I interviewed at Mirelo AI (Berlin) in Mar 2026
Interview
I did not even apply there myself; I was not really interested in the job, but was pushed by a recruiter to have an interview for a "research scientist" position. I thought it would be a discovery call where they might tell me a bit about their mission and ask me some questions about myself. Instead, it was a rushed technical interview with a lot of engineering questions and nothing about science at all. A day later, I got an automated no-reply rejection email saying there were too many applicants (despite me not even having applied there, but being pushed by a recruiter to accept the interview). I think, regardless of how that reply would have been, I would definitely not have continued the process. If I want such a toxic culture, I will apply myself directly at Amazon or Meta.
Interview questions [1]
Question 1
How attention, diffusion models, and parallel neural network training work - extremely focused on specific details, like e.g., the exact formula of how AdaInNormalization works
I applied through a recruiter. The process took 2 weeks. I interviewed at Mirelo AI (Berlin) in Jan 2026
Interview
The process involved meeting founders, an engineer, and an external consultant. Conversations were mostly pleasant.
Unfortunately they were very unserious about the hiring. After weeks of interviewing, calling references, and promising to make a decision immediately, they ended up keeping me stranded for 3 weeks with various excuses. I followed up many times and were finally able to get a response without feedback at the end that they moved on with other candidates.
I'm not sure what was happening behind the scenes but they seem to be very disorganized. I was feeling pretty excited the product and the people I met so I'm quite disappointed.
