Dont waste your time by seeing their mails calling for interviews or automated messages they keep sending reminding about the interview.
The HRs somehow feel they are the messiahs of the company and their attitude is the worst.
They do e-mail people calling for interview and they then even e-mail asking for further information and documents but thats where it ends. Never do they respond to your e-mails and its almost like you are sharing your information with an unknown person.
