I applied then was contacted by HR a few days later, she sent me an assessment qhich took about 45-60 mins math questions, spelling and multi tasking, I am still waiting to see if I get an offer.

Once you set up the interview the first one is with the recruiter. They will let you know what the job is about and run you through the basics of benefits pay and so forth. The second interview is with a hiring manager. They will ask you further questions to see what you can bring to the company and what previous experience you have. They also run you through what the job is and benefits as well as pay.
