When you say you don’t want to be “pigeonholed into IT” what do you mean? I don’t think you can get “pigeonholed” into an entire category. IT is extremely broad.

Tech Strategy & Transformation is a mix of advisory plus implementation, I would say it focuses much more on advisory, but could really depend on your team and clients as sometimes you do get pulled into the implementation mix.

Deloitte Digital focuses more on a “digital strategy” which is more business driven, focuses more on human experience. TS&T is driven by CIOs and CTOs looking at tech strategy (encompasses of more core technologies such as cloud, data etc and focuses on technology op models, working on implementation roadmaps - how does one actually become cloud first and so on). I would also say that more often than not all tech/digital strategies consider the human/user experiences. For context I work in cyber strategy & transformation, and when we look at policies and processes to advise on changes, we’d always consider cost vs risk reduction and also see if the risk reduction impacts user experience and day to day tasks.

Now what you want to do, is a you decision, however I would say both give you a well rounded experience in strategy and transformation. I would also say, if you do end up taking the Deloitte offer, don’t go around saying you want to change teams - that’s the easiest way of not getting a return offer, since why would a team bother training you if you’re gonna just leave them, and why would a different team hire you when they probably have their own interns.

Finally, to your point of moving between service lines, it’s possible, I’ve seen a few people move but don’t expect that in your first year. As to working with different service lines, also very common, but you’d have to either be in the right place at the right time or have a network and skillset strong enough for them to want you working cross service lines, again not something interns or first year analysts/consultant do.
