Tax Transformation Consulting Summer Vacation Scheme Intern Review

You’re staffed across several live engagements at once rather than one project, so most days involve switching between three or four different pieces of work. On a global compliance engagement I track filing status across dozens of entities in around thirty countries through a compliance platform. That means keeping the tracker current, spotting where local information is missing, and chasing member firms directly to close the gaps. On a public country by country reporting workstream I’ve been pulling and sense checking entity level data alongside a US based team, which usually means an early start or a late call.
The bulk of my hands on time goes into data work in Excel and the client systems, reconciling what the platform says against what we’ve actually received. Beyond that I draft slides for internal and client discussions, prepare materials ahead of calls, and write up meeting notes. I’ve also done testing work on a return to provision engagement, which is detailed review rather than build.
Two things outside the client work. I take notes at our team catch ups and write them up for the practice newsletter that goes to everyone in TTC. I also built and presented an internal discussion deck on public country by country reporting over Teams, which meant getting comfortable explaining the rules rather than just processing the numbers.
The consistent thread is that you’re given real work with real deadlines and expected to ask when you’re stuck rather than sit on it.

More than I expected, with a sensible ceiling on it.
The work was live client work from week one, not a side project built for interns. On the global compliance engagement I owned the filing tracker, which meant the team relied on it being accurate. If I missed a gap, it showed up in the status reporting. I was also emailing member firms in other countries directly to chase information, so I was the point of contact for those threads rather than drafting something for someone else to send.
The clearest example was the internal deck I built and presented on public country by country reporting. I was given the topic and left to research it, structure it, and deliver it over Teams to people far more senior than me. Nobody wrote it for me.
That said, the responsibility came with review. Everything client facing was checked by a senior or manager before it went out, and I wasn't signing off on anything or making judgement calls on technical positions. That felt right. The trust was in getting the work done properly and flagging problems early, not in being left unsupervised.
What surprised me most was that if you deliver on something, you get given more. The scope of what I was handed in week four looked very different from week one.

Both, though the bigger shift was in the existing ones.
The genuinely new skills were technical. I'd never worked in a compliance platform before, and learning how entity level data flows through one changed how I think about tax work. It's a data problem as much as a technical one. I also came in knowing very little about public country by country reporting and had to get to a point where I could explain the rules to a room, which is a different standard than just understanding them yourself.
On the Excel side I was already comfortable, but reconciling messy data from thirty odd jurisdictions is a different exercise from clean coursework data. You spend more time working out why two numbers disagree than doing the calculation itself.
The bigger development was in how I work. Running several engagements at once forced me to get properly organised about prioritising, because managers don't coordinate with each other on your behalf. You have to be the one asking whose deadline moves.
Communication improved too. Chasing member firms in other time zones taught me to write emails that are short and specific, because a vague request gets a slow answer. Presenting to seniors made me a lot more comfortable with being questioned on my own work.
The skill I didn't expect to develop was knowing when to ask. Early on I'd spend too long stuck on something. By the end I was flagging it in ten minutes.

A lot, and it was structured rather than left to chance.
The formal side is a people leader and a buddy. My people leader is an Associate Director who I met with regularly to set objectives in week one and check progress against them. My buddy sits closer to my level, which made him the person I'd message with the small questions you don't want to take to a director. Having both mattered. The two relationships do different jobs.
Day to day, the support came from whoever I was working with on each engagement. Because you're across several at once, you end up with several people invested in you rather than one. Managers were generally quick to answer, and the culture is that asking early is better than guessing. Nobody made me feel slow for not knowing something.
There was also a mentor/buddy who'd introduced me to the practice before the scheme started and kept checking in throughout, which helped with the wider questions about the career path rather than just the task in front of me.
The one thing I'd say is that the support is available rather than pushed at you. If you sit quietly and don't ask, people are busy enough that they'll assume you're fine. The interns who got the most out of it were the ones who booked the coffees and asked the questions.

The working day is broadly 9:30 to 5:30, and people actually keep to it. What stood out is that if you’re still online past that, someone will check in. Not to praise you for it, but to ask whether something’s gone wrong with the workload. Long hours are treated as a planning problem rather than a badge. The senior analysts on my team are mostly doing 35 to 40 hours a week, which was not what I assumed professional services looked like.
The office itself is hybrid, so the days you’re in tend to be the social ones. There’s a genuine effort to make those days worth the commute rather than just a desk somewhere else. I got involved in the department football league and put together a World Cup quiz for the team, and both of those were welcomed rather than tolerated.
The atmosphere is collaborative more than competitive. Because everyone is staffed across multiple engagements, you’re constantly working with different people, and nobody has much incentive to hoard information. People answer questions from juniors quickly.
The one honest caveat is that it’s a big firm. You have to be proactive about building relationships, because the structure won’t do it for you. But when you do reach out, people say yes.

Genuinely enjoyed it, and my main complaint is that five weeks is not long enough.
The thing I'd underestimated is how much more engaging real work is than coursework. On a problem set you already know there's an answer. On a live engagement you're reconciling data that doesn't agree and nobody has checked it before you. That's a much better feeling when it lands. Being trusted with the filing tracker on a global compliance engagement in week one set the tone for the rest of it.
The people made most of the difference. I came in expecting professional services to be sharp elbowed and it just wasn't. Everyone from my buddy up to partner level gave me time, and the culture of asking early rather than struggling in silence meant I stopped being nervous about it fairly quickly.
The frustrating part of a short scheme is that you leave mid conversation. On something like public country by country reporting I'd only just got to the point of understanding the mechanics well enough to be useful, and then it ends. Same with the compliance work, where the interesting bit is watching a full cycle through rather than one slice of it. Five weeks gets you to competent on the process. It doesn't get you to seeing what happens at the other end.
Which is really the best endorsement I can give it. I was disappointed it finished, not relieved. If it had run another month I'd have taken that without hesitating.

Yes
