They didn't give me any specific reasons. The recruiter called me one day after my video interview. She only told me they didn't think I was a good fit. In the interview, I finished the coding questions in 30 mins. Then I just had a chat with the interviewer. The conversation went fine. He told me he was full-stack eng and worked on frontend. I asked him whether he worked with Benjamin De Cock, a stripe designer I admire and if he could share some stories. He said yes but didn't want to share stories.
