I've been asked to appear for an interview for the Capability Network Talent & Organization Team for the role of instructional design Analyst. What is the interview process like? How many rounds are there and what happens in each of the rounds? How should I prepare?

Generally 2 to 3 rounds in accenture.

Its all depend about the capability and managers.

Had the 3 rounds, first was the HR round, second was the technical round and the third round was the face to face with the Manager.

Interview process is pretty simole. However from document submission to joining they take time and one may need to follow up for that.

It's very good interview procedure and it's good to enjoy Accenture interviews.
I have been working here more than a year and its everything good here.
Work place and even managers​also very helpful and understand your situations​.

2 rounds of interview will be there.
Soft skills are more important than your study skills
