When did he start the job? I’m guessing this Sept?? You said he’s only actually done 4 full weeks of work so far? If yes, it’s very early days. As a previous poster said, the Big 4 can be brutal and more so if you’re in a project team that are clearly in the shit right. No-one is going to be at their best in that situation as everyone is under huge pressure. He may not be the only one crying at home in the evening!
It may not feel like it at the moment but this is a huge learning opportunity for him. Quite often the best way of learning is by experiencing how things shouldn’t be done and being completely in the shit. Not fun at the time but OMG you learn fast and those lessons will make you so much better at your job in future (even if you don’t appreciate it at the time).
I started out as a grad in Big 4 Audit. It was a long time ago but it was foundational for me. Would I want to do it again? Hell no! There were some utterly miserable moments and I also found it incredibly lonely as I had zero support (my assigned coach/mentor was clearly marked as on his way out the door and he had zero interest in interacting with me). First job as a grad is almost always a shock to the system. A full-on job is a bigger shock. A full-on job that also comes with professional exams that you must pass to keep your job is huge pressure. It’s not for everyone. We were told that we should be studying 30 hours/week on top of our full time client work. Some of the client work was intense. On one client (big name multinational) we were told that the only person who gets Saturdays off is the manager because he was Jewish (!). On another client I had to stay on my own in a dodgy B&B Mon-Fri in a not very nice small town and had to battle through protesters at the gates to the client’s office every morning. I could go on and on as there are plenty of horror stories. But also some incredible experiences!
I think it’s early days for your DS. I don’t want to be unsympathetic but he needs to toughen up. Be a shoulder for him to cry on but he also needs to think about what he could do differently to affect the outcomes. Because ultimately the lesson he’s learning right now is that it’s all about the outcomes. No-one is going to hold his hand (unless he’s very lucky). It’s sink or swim.
For example, he finds a problem with the test so the test is no longer valid/meaningful but he doesn’t get timely direction on next steps from his wider team. Maybe in their eyes he wastes an afternoon doing nothing whereas in his eyes he’s stuck and waiting for them to respond/direct him. So when he finally speaks with them (or is being shouted at), he needs to say that he raised it to them immediately and needed a decision/direction as he was blocked, and going forward what is the best way of communicating this to them so he doesn’t lose time (but he knows how busy they are). Ask them what he could have done differently to be more effective. He needs to work out the best way of working with them. That might be he has a quick 10 min call/checkpoint with them at 1pm every day, or when he emails them he makes it clear in the title that it’s URGENT: RESPONSE REQUIRED ASAP or BLOCKER IDENTIFIED. This is all pretty basic stuff when you’ve been working for a while and his team probably don’t even realise that this may all be new to him.
He will have worked hard to be accepted as a grad in the Big 4. Don’t throw it away so soon. Give it at least a year (and get through the first set of exams) and then see how he’s feeling.
Failing that, remind him of the great Victor Hugo quote from Les Miserables:
Even the darkest night will end and the sun will rise
