Questions about VA employment process

Hello Social Worker Redditors I received a call from a former supervisor who informed me of an opening at the VA for a HUD/VASH case worker. I've heard the process can be long and I hoping someone can answer my questions so I can know what to expect.

• For starters, this position is called a "direct hire"... what does this mean?

• What should I expect to be asked during my interview? Will I need to know military terms (I have no experience with military acronyms)

• What happens after I'm interviewed? Will I need to fill out an application? I only sent in my cover letter and resume

• I've heard I need to write a narrative... what does this entail?

• Does the VA do pre-hire drug screens? (I only ask because I am on stimulant medications for my ADHD which makes me nervous to tell employers based on past experience)

• Do I need to include traffic tickets under my past offenses?

• What should I know about the VA and how they treat their employees?

• How are the benefits and is there a probationary period?

Any help would be greatly appreciated! THANKS REDDIT
