Just finished the Deloitte engineering manager interview loop for a role in their Government and Public Services tech practice. Took about four weeks start to finish. Posting this because I couldn't find detailed info anywhere and had to piece it together from scraps.
The process broke down into four stages:
Stage 1: recruiter phone screen. About 30 minutes. Mostly background, why Deloitte, what kind of team size I've managed. Nothing technical.
Stage 2: hiring manager call. One hour with the practice lead. Half was just a conversation about my experience building and growing teams. He asked specifically about how I handled underperformers and how I balanced delivery timelines against eng quality. The other half was him selling me on the role, which honestly felt like a good sign.
Stage 3: technical panel. Two engineers on a video call, 90 minutes. No leetcode. They asked me to walk through an architecture I'd owned end-to-end, then probed hard on trade-offs: why this database over that one, how I'd have done it differently now. Then a few situational questions about on-call culture and incident response at my current org.
Stage 4: senior leadership interview. One hour with a senior manager and a principal. Behavioral-heavy. STAR format throughout. Questions included: a time I had to deliver bad news to a stakeholder, how I set team priorities when everything is urgent, how I've handled a situation where my team's tech direction conflicted with what a client wanted.
For the Deloitte consulting context specifically, know that the client-delivery aspect matters a lot. They want to see you can manage expectations upward and outward, not just internally. "Your team ships, but the client relationship also ships" was how one interviewer framed it.
Offer came 10 days after the final round. Happy to answer specifics.
