I wish I could tell you that it won't affect you, but it will. At several companies I worked for I, as a hiring manager, wouldn't even get to see your resume or application if the suspect company was a recent (< 5 years) employer, you'd be filtered out by software, recruiting and H/R.

If there's an active criminal investigation involving the company, you'll be suspect, fairly or not.

If you're looking to leave, I'd recommend finding direct connections in candidate companies who could "sponsor" you through their H/R filtering systems, just so you get a chance to get an interview without the bias of whatever's going on at your current company.

Impossible to know to long-term damage just now...

Think other scandalous scenarios-- Theranos/FIFA/VW-- all of those firms had good, honest, hard working folks who were otherwise blameless.

Generally, it's a good idea to address a possible blemish upfront with a potential employer. Make sure your story is solid. You'll want to have superiors & colleagues who can vouch for your work and character. As time goes on, memories will fade. Switching industries may also be a smart play. Fortunately, development work is in demand across every sector imaginable.

I wouldn't worry about it as a resume blocker. I wouldn't try to throw your department under the bus if someone asks either. doubt it comes up but I would answer with something like "there's a lot of great people that work there and I wasn't directly involved any of the decisions or work that lead up to it."

you might also want talk about what you learned from it.

Not talking about something sensitive is a safer route. The risk of saying something bad outweighs the off chance of a reward.

sorry I should clarify I meant only if they brought something up about it.

Depends on details of scandal...

1) was the whole company a fraud? Aka You were a trader for Bernie madoff or was a scientist at Thernos
