I applied online. The process took 1 week. I interviewed at Slack (San Francisco, CA) in Sept 2017
Interview
Applied online on their website. Recruited emailed showing interest. Scheduled the call for initial screening. Recruiter asked my background and explained the process. Surprisingly got a reject email right away. Not sure what happened. If profile did not match then what was the need for the screening call?
Asked general questions about your career so far on a casual phone call before, the main interview was a series of questions and 2 test questions which weren't too difficult.
