There was a timed test to test your accuracy. After the test results were back half the room of applicants were asked to leave. Then the remaining were told they had passed the test. Then the interviewing began. I was interviewed by 3 different people.

Pretty standard interview. Just go in professionally and you should do just fine. Also, dress professionally. The interview is done by one or two people depending on availability. It takes around 15- 30 minutes depending on your answers and follow up questions.
