First, I received a phone call. The job description, including salary, were described to me. I was being invited to take a test, with the intention to be hired a month or so after the phone call. There were scheduled tests in a few locations. I chose a location (a library) and time. I brought my resume, a list of references, a pencil, and something to keep myself entertained, such as a book. A bunch of people took the test together. It was very easy. A sample test is available at census.gov. Next, each of us was interviewed one by one. I was asked to read a sample survey and annunciate clearly. I was also asked to answer questions using examples of my experience, including describing what happened, what the problem was, and how I solved it. Following directions may have been more important than the experiences described.
