Infosys HR call

This week I got Infosys HR role. She was inquiring about general questions like CTC, role, technologies your interested in etc and told would send the interview link if profile is shortlisted.

Then I got a mail saying infosys survey which was asking for availability for interview on 26th like the time slot and the technologies I am interested in, location.

This was very abrupt and I don't remember applying also.

Has anybody else got this. If yes, were you able to able to go across the interviews.
