Interview
It was a long interview process but the people interviewing me along the way made it an enjoyable experience. The interview rounds were intense but not impossible and there weren't any unusual questions to try and catch you out.

Interview
The hiring process involved filling in an online application, performing a test of mock customer emails, a HR screening, a phone interview with a hiring manager followed by an on-site session of 2 interviews, an additional mock email test and a chat with a senior level manager. Everyone was super helpful and professional. The interviews were relaxed and gave me a great insight into the company and the people working at Slack.

I applied online. The process took 3 weeks. I interviewed at Slack in Nov 2019
Interview
Fairly easy coding challenge that consisted of 3 questions. Behavioral 30 minute phone interview to get to know you and let you know more about the position. One more 45 minute behavioral phone interview asking more about your experience but still no technical questions. Great communication in between interviews and the interviewers were all very friendly.
