Just go in and wait for your time for the interview, you'll be seated and have a one of one interview. Once that's done they'll call you if you're hired.

I applied online for a position. It took them more than a month to contact me via phone. They did a little screening with a few questions on the phone about my current position and roles I have, and then scheduled me for an interview the next week. They said they would contact me within the same week either way, to which they did not. They also said I could e-mail them with any questions I had, to which I did and to follow up, with no response. Instead I got a rejection letter in the mail 3 weeks after the interview.
