One initial phone "chat" (ie informal interview with one person), which was about 15 minutes long). Then about a week after that a more formal interview with two people (about 45 minutes), and finally a third interview a week after that with an additional person (about an hour). HR Manager/recruiter was very communicative and easy to reach, I greatly appreciated not being ghosted even though I didn't get an offer. During the last interview one staff member was 15 minutes late, and was rather rude and curt during the whole process. I also got the sense that some people who interviewed me had not reviewed my resume or application at all. It was a poor reflection, but overall I still had a positive interview experience.
