Lengthy but straightforward - I was interviewed in 2022 over the course of two months. Recruiting team was open and transparent about the process and I was offered a position after four rounds.
Met with the recruiter who asked me several questions. Made it to a second interview with the local office lead. I thought it went well but I never got a follow-up call, even to tell me that I would not be considered.
Slalom interview process is very welcoming. They weave in questions into conversation verses more formal setting. Everyone there is very transparent. I had 2 Microsoft Teams interviews before getting offered the position.
