I’ve got an offer for a corporate strategy role at a Fortune 500 tech company, and I’m trying to get a realistic picture of what I’m walking into. I’ve read the job description, talked to the hiring manager, and they made it sound like I’d be “owning strategic initiatives” and “acting as a thought partner to the C-suite.”
But I know that job descriptions are fiction, and I want to understand what actually happens in those first 90 days. Are you building relationships? Are you expected to have impact immediately? Do you hit the ground running with a strategic project, or do you spend three months learning the business?
I’m also curious about the culture shock, to be honest. Consulting moves fast—decisions happen, you implement, you move on. I’m assuming corporate strategy is different, but I don’t know how different.
For anyone who’s done this transition, what surprised you most in those first three months? What do you wish you’d known going in?
First 90 days? ur basically a tourist. Theyll smile, tell u the strategy, then u’ll watch them ignore it for six months while they reorganize for the third time. spend those 90 days figuring out who actually makes decisions versus who just talks about decisions. thats ur real onboarding.
ooh this is so helpful to ask!! id b super interested in hearing the real answer bc ive got an offer too and im rly nervous about the culture thing 
You’re going to be amazing! Your consulting background is such a gift. These first 90 days will fly by and you’ll feel right at home!
I joined a strategy team at a large financial services company, and what threw me most was that my first 90 days didn’t follow the consulting playbook at all. I assumed I’d come in, identify some big problems, and start working on solutions. Instead, I spent the first month just understanding why things were the way they were. There were historical decisions, political dynamics, and functional constraints I didn’t see until I was on the inside. The wins in those early days came from small stuff—understanding the budget process, learning who actually advocates for strategy versus who just tolerates it.
Research on executive transitions shows that consultant backgrounds tend to struggle hardest in the first 90 days due to misaligned expectations about decision velocity. On average, consultants transitioning to corporate strategy report that initial projects take 2-3x longer than anticipated. The most successful transitions involve spending weeks two through four explicitly mapping decision authority and governance structures. Your analytical strengths are valuable; your assumptions about timeline aren’t.
also tho—if theyre smart theyll have u on a quick project early to test u out. if that project stalls after week 3, thats not ur fault. its the org. dont internalize it like u failed. just means the ground is shakier than the offer letter suggested.
so like do u actually get assigned a mentor or do u have to figure everything out yourself??
Most corporate strategy functions assign a buddy, though not always a formal mentor. Be deliberate about who you build relationships with in those first weeks. You want advocates and translators—people who understand both the strategy function and the broader organization. The consultants who struggle most are the ones who retreat into their own competence rather than spending time building political equity. You’re right to ask about culture shock because it’s real. In consulting, friction typically means you optimize the solution. In strategy, friction often means you need to accept the solution and make it work within constraints. That’s a different muscle entirely.
Honestly, you should feel so proud going into this role! You’ve got the skills. Just bring your best self!
One thing nobody told me: go to the social stuff early. Not because the happy hours are fun, but because that’s where you learn what people actually think versus what they say in meetings. I went to a couple early on and overheard a conversation about a failed initiative that completely reframed how I understood the team’s actual risk tolerance. Those conversations are gold for calibrating your approach.
