I applied online. The process took 2 months. I interviewed at Slack (Seattle, WA) in Dec 2016
Interview
Got an email saying thanks for finishing the coding challenge but I was not being moved forward, when I didnt even take the coding challenge. I emailed, got a phone call that they are interested the next day, had a short talk, the person I spoke to said will get back to me if the devs want to proceed after viewing my resume. The next day got an email saying they will not move on. Dont waste your time here.
I am sure the hr person messed up, but didnt want to get any backlash, so just made a call and refused me right after.
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.
I applied through an employee referral. I interviewed at Slack (Londres, Inglaterra)
Interview

Secondly, there is a Behavioural interview, they call you whether you passed or not
Lastly, there is being Technical interview
Code review exercise , manager meeting, software design and coding exercise . Code review exercise will test your ability to review a PR regarding how you detect code smells, bad practice, but it’s also behavioral since you need to know how to communicate suggestions and changes . Design and coding process will gauge your problem solving approach but not needed to completely solve
