The second piece to this question- what do people think of lying on your resume? I can't stand it- but I think it may be common place.
Thanks for your thoughts!
What would I do? Not a damn thing.
It's not your job to right every injustice in the world; and it's questionable if there's any injustice here in the first place. Ok, she lied on her resume... big deal, getting a job is one thing, but keeping it is about performance. If she - in the end - can DO the job she was hired to do, does the lying on the resume bit really hurt anything? Not that I'm advocating lying, I'm just saying that "what's done is done" and that it's not your place to get involved.
Either way, why are you even thinking about this? This is wasted time you could have spent doing something productive.
Even so, the resume has little to do with a hiring decision once getting someone passed the initial bar. Hiring is completely dependent upon the interview and the background check. The resume is not used for much more than a sanity check.
I am not a lawyer, but it seems to me this is really risky for you and doesn't provide any benefit other than revenge.
If your knowledge of the company is material, then the most you'll want to do is possibly telling them to do their own fact-checking. I.e., if it's your best buddy's startup[1], then you call him or tell him face-to-face, with no written record. Use tone (sarcasm is good here, but when isn't it?) rather than word choice to convey that not all is as it seems.
It's possibly grounds for a slander or defamation lawsuit if your ex finds out that you called potential employers and called her a liar, so think about whether you are still carrying enough baggage that it's worth exposing yourself vs. using this as an opportunity to move on.
[1] In which case, your first words should be,'hey, bro code violation–stay way from exes!' Then you get to punch him once in the stomach the next time you see him.
Everyone puts their best face forward on a resume - and will usually stretching the truth a bit. But most don't engage in outright fraud to land a job. If she is doing that, well she may be facing liability down the road.
It's impossible to discern the severity of the lie from your question alone - for all I know you could be nitpicking douche-bag - OTOH she may be a conniving, money-grubbing harpie. Details, please.
2. A lot of times, for higher level positions, it'll catch on fast and it's not uncommon for people to be let go.
3. As to whether or not you should let the company no, this part is tricky. The right thing to do is obviously tell the company whether or not she could perform the tasks. The problem though is it may ruin your relationship. It would have been better to prevent it from happening but what's done is done.
In reality it's not really your place to interfere but you're going to have to make a judgement call on whether or not you want to step in on this.
According to Dilbert at least, lying is common...
Your Ex may turn into a valued contact in the future, or might be your future boss, you never know. If they lied then it will really depend on whether they can do the job or not, and a resume only gets you in the door, interviews are what gets you jobs anyway.
That said, I once received a resume from someone who listed as one of their past employers a company I'd also worked for. He listed his work there as being on a project that I'd worked on, and partially led. One with less than 6 people on it. One that happened without him being involved at all!
I was amazed at the nerve. Would have been easy to call the company if we'd been reference checking and found out, but worse, I'd worked there so I knew right away it was a lie.
We uninvited him from his interview.
That's too bad. It would have been a very interesting interview.
