Hi there,
Absolutely! I successfully interviewed with PwC's tech practice, have a tech/IT background paired with strategy, and have helped more candidates than I can count in the tech consulting space - feel free to reach out directly to me!
What to expect in general
You should absolutely expect cases/questions to be much more tecg focused. As such, you should practice tech cases. However, you should still be prepared for "classic" cases as well.
Furthermore, they would absolutely expect you to leverage your existing experience in your answers.
As mentioned, I interviewed with PwC in their Technology practice and I can tell you that it felt much less "case-y" than the pure strategy firms. As such, just be prepared to not be taken through a whole case. As an example, off the bat I was asked "How would you organize a backlog of IT enhancements". Of course, I used my judgement to not treat it like a case and just went through the classifications/process I would use and why. Make sure to read the cues here!
How to Prepare
It's quite tough to find adequate tech-focused cases.
That's why I created 2 (see below). Of course, I have more, but those are reserved for my coaching sessions :)

Both of these are based on real-life cases and have a tech-focus.
