Trending @Wipro; New joinee, some info needed

I will be joining Wipro in Feb 1st week as Technical Lead in Gurugram. They told me that my office address is Sector 20.

1. Is this a training centre and my location will get changed?

2. What's WFH policy or hybrid policy for new joinee?

3. Is there any probation period, if yes, then can I take leave and do WFH for 2 -3 weeks?
