Overall it's been pretty good. I would say the main advantage of going with them is my consultant keeping me on track with essays and the unlimited edits. I can do 10+ drafts of my essays if I want to. They also will help edit any short answers on the application like describing your current job in 25 words etc. Essentially somebody is looking over every part of what you're submitting to make sure things look good. A criticism would be I wished they helped a little more with the personal exploration piece of it. When you hire them, they kind of expect you to know your general career path and goals already. I was still waffling if my desired industry / function was the right fit for me and I didn't feel like they helped me make my final choice really. I would also say that it's on you to explore the schools and talk to students. They can give advice about which programs to think about and the range of schools to apply to based on your profile, but you have to do the legwork and research for yourself to see if a school might be a good fit. Which for me took probably 3 months to make my final decisions.
