Slack interview questions

I applied through the website and got an email from the recruiter after one day or two with a writing exercise that must be delivered within 48 hours. The recruiter called me after 1 day for a quick phone interview and said I was good to jump to the next stage. I was interviewed by a Hiring Manager. He asked me 3 questions and then left the remaining time to ask him questions as well. I heard from the recruiter after one day or two saying that the HM was happy with my interview and that I was in the final round. The final round is a competency-based interview with 2 managers, 1 TL, and a written assessment. I had a very positive experience with Slack as they respectfully follow-up in a timely manner and always set your expectations. The recruiter provided constructive feedback to perform more successful next time. I felt very respected and valued by the whole team.
