'No firms are. you cant compare Big 4 and MBB - they really are an ocean apart in brand. What you need to get you head around is that MBB occupy a very specific tier in consulting, one almost removed from the main industry and best seen as a sub-set in their own right.' So if you're saying MBB have carved out their own market, where would you classify firms like Oliver Wyman, ATKearney, Booz, LEK, OC&C etc compared to MBB and deloitte? Also if it is quite uncommon for Deloitte employees to go to MBB, what do they usually do if they choose to leave the firm? And if they don't how long does it take to make partner and what % actually make it? I've also seen some discussions of whether Deloitte is an up or out culture, thoughts on that?OW, ATK etc are usually called 'tier 2' - in reality their people are as strong as typical MBB hires but they lack the brand. Also these firms each tend to be known for a specific proposition - ATK for its operational work, LEK you would go to for transactions due diligence and modelling, OC&C very strong on consumer, OW probably the strongest FS consulting name worldwide. But MBB is a club of 3 firms and no one else is getting in. People who leave Deloitte go all manner of places - there is a constant rotation between the Big 4 as the continually poach from each other, there are other main consulting firms or consulting arms, and midcap specialist and boutique firms. They also go client side. It depends on what they have been doing at Deloitte really. there is no one size fits all answer.Making Partner? Well think big. Actually making Partner in a firm like Deloitte is really about getting a chair, like winning tenure at a university or a board seat at the subsidiary of a major corporate. Its a big win, but its big fish in a pond which is in fact part of a bigger pond, fed by bigger rivers. Its not the done thing these days to join as a grad and stay until partner, not least because most will leave anyway, and partners need to be rounded, grounded, and commercially viable as business originators in their own right - hard to do with just one firm on your CV and a limited professional rolodex. But hypothetically lets say you joined Deloitte as a grad and reached partner. It would take you, all being well, 5 years to Manage grade, then you have to start winning business, step up to SM, but allow for traffic as this is a major bottleneck. So lets say 8 years, you are a legend on sales and delivery, and have sponsorship from the business, Director in 10. But you need to cash in to the partnership and have a young family and an expensive wife. With some outside investments and a bit of planning you could - feasibly - make it in 15+ years. Feasibly. The reality is youll want to leave Deloitte after you get through analyst grade to shake off your trainee tag so you can start to get real recognition from peers and clients. After that, in the UK/EU market you will be wanting to move every 3 - 5 years or 2 promotions whichever comes quicker.Up or out? Yes. But not usually as brutal as audit/accounting as there isnt the black/white exam pass/fail stage/gates to go through. More likely to be 'managed out'. Not that you will feel any better for it.
