Engineering Manager, Site Reliability Engineering (SRE)
onsite
· Difficulty 4/5
Candidates report a recruiter screen first, followed by a technical screen with an engineering leader focused on scope, people leadership, and prior experience running reliable services at scale. The process typically includes a deeper technical interview that evaluates incident management, reliability strategy, and systems thinking, often framed around Slack-like workloads such as real-time messaging, APIs, and high-availability storage and networking. A virtual onsite (or onsite-style loop) commonly follows with multiple sessions: system design for reliability, operational excellence and incident response, collaboration with product engineering, and a dedicated people management interview. Interview loops often include a cross-functional partner conversation with security, platform, or production engineering to assess how the manager drives alignment and manages risk tradeoffs. Final steps usually include a culture and values conversation plus references, with timelines often spanning several weeks due to panel coordination.
Describe an incident you led end-to-end. How did you manage communication, mitigation, decision-making under uncertainty, and the post-incident follow-up?
How would you design an SLO and error budget strategy for a real-time messaging feature where customers expect low latency and high availability across regions?
A product team wants to ship a feature that increases operational risk. How would you structure the conversation and decide whether to block, gate, or proceed?
What reliability signals would you monitor for Slack-style web, mobile, and API clients, and how would you reduce alert fatigue while maintaining coverage?
How do you hire and develop SREs with different strengths (automation, incident command, performance, capacity planning) while maintaining a cohesive team culture?
Sales Development Representative (SDR)

· Difficulty 3/5
Candidates report starting with a recruiter screen focused on motivation for Slack, baseline communication skills, and eligibility details, often scheduled within a week of applying. The next step is typically a hiring manager call that tests prospecting fundamentals, coachability, and how the candidate explains Slack’s value to different stakeholders (end users, IT, security, and procurement). Many processes include a role-play or mock cold call, sometimes paired with a short written outreach exercise (email and call talk track) designed to mirror Slack’s multi-threaded, persona-based selling motion. A panel round may follow with cross-functional partners such as an Account Executive or Sales Enablement, emphasizing collaboration, handling objections, and operating in a metrics-driven environment. Final steps often include a values and culture interview aligned to Slack’s emphasis on empathy, customer focus, and clear communication, with references completed shortly after.
