Interview with HR, assessing soft skills and English language level, technical assessment with two senior team members - quick technical questions followed by coding task, around 1.5h, meeting with head of the HR and a project manager.

I'm not bitter over not receiving an offer. It's the way my interview experience went that should raise a red flag. It was disjointed. A senior member of the development team contacted me directly instead of a recruiter. I therefore had a technical interview and got a code project before the intended "initial" interview with the recruiter. I was told that they were experimenting with their hiring process, but the recruiter's word choice and tone made it sound like this should not have happened. Still, the recruiter projected a positivity that made me feel I was as good as hired. However, he/she was obviously frustrated with the chaotic hiring process (and perhaps his/her lack of control over it). Especially when I was accidentally sent the final step of the process (a personality assessment) by someone else in the hiring department. The recruiter called me the next day to rescind the assessment, but said it was because I was sent the wrong one instead of saying I shouldn't have been sent one at all (which is the truth). He/she was also surprised that I had completed it and then said he/she would check to see if I had been sent the right one after all. Very strange. A few days after this call I was sent a rejection email with no apology for the mistake about the assessment. This whole experience left me feeling (key word, feeling) like a casualty of an interdepartmental power struggle. I doubt this is true (there are perfectly valid reasons for me to not get an offer after completing any step of the hiring process), but having the mistakes in the process spun instead of truthfully explained left a bad taste in my mouth. Honest bad news up front is better than being blindsided after multiple attempts to spare my feelings.
