Took the Accenture online assessment a few weeks ago while passively exploring options. Sharing the breakdown because honestly I couldn't find much recent info when I searched.
Platform: Codility. They emailed a link with a 5-day window to complete. I had 90 minutes once I started.
Format I got: 2 coding problems + 1 debugging problem. Problem 1: array manipulation, medium difficulty. Think "find the minimum operations to make all elements equal" type stuff. Nothing exotic. Problem 2: involved a basic graph (detect cycle or find connected components, I forget exactly). Medium again. Debug problem: they gave you broken code with a few bugs and you had to fix it in about 15 minutes. The language was Java but I've heard you can pick your language in some versions.
Difficulty: Honest answer is Leetcode medium. I didn't see any hard-tier problems. There's no adaptive difficulty that I noticed.
What I didn't see: No SQL questions, no system design, no multiple choice trivia. That might differ by role though. This was for a software engineering position in the commercial tech practice.
Time pressure: 90 minutes felt tight but manageable. I finished with maybe 10 minutes left.
Score/threshold: No idea what the pass bar is. I passed and moved to the phone screen, but I don't know my actual score.
One practical note: the coding environment in Codility is fine but not great. Test your environment before starting. I wasted 3 minutes figuring out how to run the tests.
