I was applying at jio for a position saw this. Is it okay to give aadhar lan number before getting selected?

Select "No" in do you have an aadhar card. This are just ways to siphon personal data.

I don’t get why this is required. If you’re unsure just give masked values 1234 xxxx 4321 for exampld

No

Don't

Same for makemytrip job site.
I end up not applying for these kind of companies

You can put, virtual adhar id
