Sabbatical ( leave without pay) vs Resignation

Any working professionals here ?

I have a few questions…

Which would be better? Taking a sabbatical ( leave without pay for 2 years) or resignation?

I am considering sabbatical as a backup incase the market becomes miserable…

My Question is based on the following sub queries:

Will having a job at hand affect my internships and placement chances ?
Will I be given less preference?
Can I even sit for internship interviews with a job in hand?
Will that extra experience cause some problems during final placements ?

I would be very grateful if any alumni or any working professional in this group could discuss this issue with me…

Thankyou!
