Shady interview at thane

For the context: I am a second year student looking for internships and recently I had applied to various jobs in my locality. I got a call from a lady saying my profile was shortlisted for an interview and the company is tech Mahindra ( I never applied for it lol) But still they gave me the address and I went there. Even in the waiting room there were only 2-3 other participants and one invigilator ( from that point I started having doubts) Then my name was called and I was then taken to a small cabin. Usually what I've seen in online videos about internships is that both parties firstly introduce themselves and then they start the process, but Daaamn this women was in such a hurry. I timed My answers in my head but she interrupted every 1 min and asked me another idk if this happens in interview but wait theres more lol Then after everything that has happened she directly said I was ready to work in tech Mahindra with in hand salary 20k etc etc I was like wow I never knew I was that in demand 😁 ( this confirmed my doubt lol) Without even asking properly about my data analyst projects she accepted me. Ahaha So when everything had ended I asked her what's the next process when I would be called for the other interviews she said this "FISRT YOU HAVE TO PAY 2000 IN ORDER TO CONFIRM YOUR SEAT" I asked her if I would just pay you from my first salary, and she said no😆 This interview was taken at Gokhale road, beside MacDonald prachi store paradise office 609, Thane West 400601, Maharashtra. I still have their contact with me should I just pay? Has this ever happened with anybody?
