It was a tough process. I had 6 steps in total including phone screenings. However, my recruiter guided me really well through the whole process. The first steps are done over the phone, you then move to a skills test and 3 onsite interviews. Preparation is key, have your research done on Slack and be ready to be able to give a great overview of your work history.

30-minute video conference screen with recruiter, take home writing assignment (takes 3-4 hours), another video conference screen with the hiring manager- only got to this step before getting the "no." Recruiter was great. The take-home assignment was time-consuming but easy. Head of SMB seemed very sharp and intelligent-though I was thrown off because she was a bit abrasive. Asked a few questions about experience and jumped abruptly into a role play. Overall a good experience- thing that is different about interviewing at Slack is the video conferencing piece - makes you prepared like a real interview because you can't look at notes, etc.
