I applied through an employee referral. The process took 2 months. I interviewed at Slack in Sept 2019
Interview
Applied with referral and got a coding challenge about 2 weeks after. Completed the coding challenge and about a month later, I got called by a recruiter without any prior scheduling on the weekend at almost sunset, to schedule a phone interview later the week. There weren't any confirmations through email or anything so I was sketched out. The phone interview did take place and they asked for my availability for the next 2 weeks soon after, which I filled out ASAP. I never heard back about a interview confirmation.
I applied online. The process took 2 weeks. I interviewed at Slack in Nov 2022
Interview
After being contacted by the recruiter, I was given a 4 hour long codesignal. The next step is being reviewed by a hiring manager who decides if you get an interview.
I applied online. The process took 2 weeks. I interviewed at Slack (San Francisco, CA) in Nov 2022
Interview
Got a code signal. A leetcode easy and medium to complete in 1 hour. This was for the mobile internship position. It seemed like they wanted a very optimized solution as I got rejected.
I applied online. The process took 4 weeks. I interviewed at Slack (Overlea, MD) in Dec 2021
Interview
CodeSignal - 3 Questions
Phone Interview - 30mins

Overall not a difficult, nor very technical interview. Very important to show demonstrated interest in product and working in strong collaborative teams.
