Very simple and easy. Clear by the end that I was likely going to get the position. Hardest part of the job process is getting an interview and for that you need good academic qualifications and hopefully some prior intern/work exp.
I applied online. The process took 12 months. I interviewed at U.S. Department of State (Over Silton, England) in Sep 2019
Interview
Very easy and not complicated. They're not trying to trick you. Made me feel very comfortable. Situational interview questions about the job. Very basic questions. don't try to over think the answer, just be yourself
I applied through college or university. The process took 10 months. I interviewed at U.S. Department of State (Tampa, FL) in Sep 2020
Interview
Two rounds of interviews. The first was given with very little notice (only about 2 hours to prepare) whereas the second was longer, more in-depth, and had multiple interviewers. Both were moderately challenging.
