After taking just a few minutes to read through the interview questions for the actual census I had to go through a mock census questionnaire as if taking responses from a household member but with interviewer instead. I was also asked standard interview questions such as my personal strengths weaknesses and best and worst qualities and so on.

Very easy online form, got a call the next day with some simple questions about availability and willingness for confidentiality. The job is only temporary, but decent hourly pay and a nice filler while looking for other work. You will need to get fingerprints taken before being hired, if you're contacted and offered a position. Overall, I'd recommend the process to anyone. Could be interesting to be part of something that only happens every decade. Especially in today's climate. Was told that it can be uncomfortable and sketchy sometimes, so if you're not good with confrontation, maybe reconsider.
