Went through the Deloitte tech consulting SWE loop earlier this year for a senior software engineer role on one of their government tech teams. Took about 5 weeks start to finish. Figured I'd write this up since the info online is all over the place.
Here's the rough sequence:
Week 1: Recruiter screen (30 min) Standard stuff. Background, why Deloitte, are you open to travel (yes, this is real, especially for consulting roles). Also checked eligibility for clearance since the team I was targeting was DoD-adjacent. If you're on a visa, clarify early whether the role requires citizenship.
Week 2: HireVue / async video screen Three behavioral questions, recorded. About 3 minutes each. I hate these. They're what they are. Prepare 3-4 STAR stories and rotate. Questions were something like: tell me about a time you worked under tight deadline, describe a conflict with a stakeholder.
Week 2-3: Online technical assessment 2 coding problems, 90 minutes. Leetcode medium level. One was a graph traversal (BFS), one was a modified sliding window problem. No system design at this stage. I used Python, no issues.
Week 4: Technical interview (live, 60 min) Paired with a senior consultant/engineer. Started with a code walkthrough of something I'd built, then one live coding problem (Leetcode easy-medium, think two-pointer). The engineer was clearly assessing communication as much as correctness. Talk through your thinking.
Week 5: Final round (2 interviews back to back) One behavioral with a principal, one with the delivery lead. Heavy STAR format. Asked a lot about working within constraints, client-facing situations, dealing with ambiguous requirements.
No system design deep dive in my loop. Might vary by practice or seniority level. The behavioral stuff gets surprisingly real weight here vs pure product company loops.
Offer came about 2 weeks after the final round. Timeline was long but they kept me updated. Total: 5 weeks is pretty typical from what I've heard.
