Applying 2nd time to any company

If once we are rejected, can we apply to that company again? I got rejected in statnetics when they conducted an interview last time. I got a mail from elitmus to apply for statnetics but when I tried to apply it says I already applied once and can’t apply again . If anyone had come across the same issue please suggest me any ideas.

U need not to reapply. Your application will be considered automatically. But I will suggest u to call elit and confirm, and plz let me know too.
