I applied online. The process took 1 day. I interviewed at Slack (San Francisco, CA) in May 2018
Interview
The usual: meet with SRE team tech leads, peer managers, Hiring Director. I had 7 interview blocks, 45 minutes each, all 1:1's in a conference room. They had just moved into their new building, so I was given a tour. It was nice. The interviewers had assigned modules, but many were OK deviating from their modules to dig into what they wanted, hence many duplicate questions.
Interview questions [1]
Question 1
How do you build a diverse team. (Most interviewers focussed on this)
Tell me a time you had a challenging interaction with a manager from a different team. (asked multiple ways by multiple people, but basically the same question/answer. Prepare multiple answers.)
Tell me a time when you had a challenging employee interaction (same as last question, have multiple scenarios for the same question).
Whiteboard a system you worked on, in as much detail as you can.
What would you say are your strengths and weaknesses.
What would your reports say is your management style.
