I applied online through their website. Then they set an interview for me with the CEO. It went well and he seemed friendly. Around 3 weeks later, they set the first round of the technical interview with me. The interviewer was not rude, and not friendly either. It was a fair coding question with Data science subject, and a short non coding data science question. I did the code and went well, I was not 100% sure about my answer to the next question tho. It was Friday afternoon, and 3 hours later (6 pm Friday night) I got the rejection email!!! To me it feels like they had already made their decision. Plus, I had read the reviews about their lack of diversity in 2020, and then after I checked their LinkedIn, I realized that ZERO female is working in their R&D (Or they don't have LinkedIn which doesn't seem correct to me). I found it a HUGE red flag.

We did an initial phone screen. Then we did 2 remote interviews. Last was a final day of interviews on-site for a full day with 5 - 6 people and a mix of problem-solving and behavioral interviews.
