Hi Ganesh,
First of all, congratulations on the invitation!
I would be happy to share my thoughts on your question:
- These types of phone calls are typically used for aligning on the interview process, so you would not have to prepare anything. However, if you want to know for certain, I would advise you to clarify upfront with the recruiter.
You can find more on this topic here: How to succeed in the final interview round.
If you would like a more detailed discussion on how to best prepare for your upcoming interviews, please don't hesitate to contact me directly.
Best,
Hagen
