Career fair. Straight forward interview. Questions about past experience as a field technician. Question about whether or not you are able to handle the 12 hour shift and climate element aspect of outside work.

Submit application, wait for processing, if you are lucky you get a phone interview callback. If they accept you the on-boarding process will be at least another month to do all the paperwork and get you set up to begin work. I applied at the beginning of November and didn't officially start work until mid-March. After that point there is lots of training and field trials before you officially begin field work.
