Pros
Deloitte makes sure you are extremely well prepared to face the customer and challenges around the consulting world. If you have been to other consulting firms (non-big4) you'll notice that you never got such great information to get a head start. The firm sets high standards, consistently deliver and invests heavily on their branding and make sure you are prepared to deliver that within their expectations. Top level management are extremely smart and have a great sense of vision and planning. It is quite easy to have conversations with upper management people, most people keep open door policies and they will try to help you in any way they can. Deloitte University is a fantastic facility and the company invested heavily there and all the training you get there are top notch. You will find that Deloitte is on this business to win big and if you are able to network well you will grow easily on the firm. The benefits package is very good, pretty standard across the industry. The company has multiple mobile apps which makes your life a lot easier. Timesheets, expense reports, meeting/desk reservations can be done easily from your mobile phone. There are no delays on payment of expenses unless you have something that is really out of policy. There is a hotline for ANY question you may have and they resolve everything in 1 phone call.
Cons
I have found that even with a very big network outside the firm that connected me to people inside the firm, it can be hard to get staffed. They have a system where you look for project opportunities but that system is often outdated and you can not know who is hiring for specific jobs. A lot of people, specially senior managers and partners are often way too busy to respond to your e-mail and sometimes they will not even get into a phone call with you unless someone else referred you. There is intense competition and back-stabbing happens all the time and faster than you can think. One little honest mistake spreads quicker than a great achievement. Once you have done something that others claimed to be bad, it is hard to get your image back and you won't be invited to projects. You'll slowly sink if you don't play the political game. HR and your resource manager are very nice to you, and they will try to help you to get into a project. However, you must be flexible and willing to work on something you don't master. I personally don't like the idea of begging for work while you can see everyone else is busy. However, take advantage to learn a different skill. I ended up leaving because I could not survive a political game within a small group. Work/life balance is not truly there. There isn't a way to implement this easily in consulting. However, you should never expect someone to be available after hours and to work in the weekend. Even worse is hold someone accountable and stab them in the back if they had personal commitments on a weekend where you decided on a Friday afternoon that you need someone to work on a presentation that needed to be done on Monday morning. This can be something doable for young kids but not for employees with families.
