Joined as a grad at a Big4 a bit ago. The place in question is know for being quite 'siloed', but the grad scheme was advertised as giving broad exposure to different areas across operational/finance advisory and implementation. Found out upon joining we are all assigned to one very narrow area. There was zero consultation, no option to change (a few have tried, hasn't been allowed) and many people feel the scheme has been mis-sold. At no point during the recruitment or onboarding process is this mentioned.Very difficult to join projects in different sub-areas, a lot of networking and bit of luck with timing needed. Not ideal but chose to suck it up, try everything in the book to join a project in my target area. Didn't come off. The sub-area leads will put you on one of their projects every time, and have no flexibility. Understand that it's their P&L, but long-term the attrition rate is losing them money. Hiring spree for higher grade is happening now due to this issue.I'm coming up for promotion later in the year, but still have not had the chance to try anything other than the same exact work. I have no interest in working in this sub-area and sometimes regret joining. Further problem is that projects can last 6 months plus, frequently up to a year which is very demoralising.Stupid thing is in this hiring market they could get people who actually are keen on the kind of work each sub-area does, if only they were transparent throughout the hiring process. As it is, my cohort are out the door as soon as we've done our 2 years. A shame.
