I have been working at IRS (More than 10 years)
Lack of stuffing and
Resources limited due to budget constraints
I applied online. The process took 8+ months. I interviewed at IRS (Philadelphia, PA).
the interview is a 3 panel interview, and each of the interviewers ask you a questions one by one and you have to respond. They take notes on your responses and they proceed to the next question. You have to impress most of them to get the job.
