Wow interesting discussion about Accenture. Accenture SE or SM should read this haha. I am here to share my experience too. My background and ties with Accenture is like this, fresh graduate in Engineering background. Joined Acccenture as my first job as an analyst in a resources project but has resigned from Accenture already .

Too many long replies didn't read all but capture few interesting point. I am going to just share my pure experience with Accenture as a fresh grad ex-analyst. Going to keep it short.

1. About different project with different working hours

-Yes this is true different projects and different manager have different expectations. Some managers are flexible and try to give the best work life balance but some managers are a driver character meaning they really want you to work long hours (actual quote from manager: next time let review first, don't rush off to go home at 6:30 to 7. After review need to do amendments and time goes on).
-Some projects are on a very tight timeline no choice you are pulled in and you have to work late like business developments or SAP projects
-Some managers do have their own agreement to have flexible timing for their assistants like work from home or start late go back late.
-Conclusion it depends but generally the perception that was given to me is that work late is a top performer. Leave early less performance. Partly is peer pressure which causes it. If everybody in your team (more to managers and consultants) leave at 10 or 11 everyday and you leave at 5:30 everyday the perception is different.

2. High turn over rate

-From my observation partly it is because they hire a lot of people who are not from the IT background, lots of engineers. And these people over time will find that IT industry is not suitable career path therefore leaving.
-Secondly is that if you get a shitty project your are in shit. You get what I mean.
-Thirdly is the normal one that people don't get promoted and leave.

3. Project choice

- My experience as a fresh grad you don't get to choose!.
- Take a project given to you because if you keep choosing and go without a project you are under performing because they use the system of chargeability (lay man terms how much you are charging the client aka earning money for the company. No project, no client, no money = not good)
- Most projects also keep a policy of maintaining the people with that account. You will get the chance to change project within that single account but you have no say!

Getting too long. Anyway this is my experience.
