I applied online. The process took 12 months. I interviewed at Caltrans (Rio Vista, CA)
Interview
Job posted on state job website. Apply through that. Wait at least a year to be called. You will have forgotten by time called. After the interview, it can take up to another year to be called with a job offer. Once you hire on, you are on probation for 6 months during which time you can be let go for any reason; this is rare. It is a lengthy process to get hired into CALTRANS.
Interview questions [1]
Question 1
This will not be challenging. The questioners know nothing about marine subjects. They are more interested in your ability to get along with others.
