NDA
Jobs routinely have non-disclosure agreements. I've lived a very private life and as a wife, mom, sister, friend, etc. everyone acts like I signed a non-disclosure agreement about the relationship but I'm not entitled to money or a useful entry on my resume for it.
My son once complained to me that he was certain some guy ruined every project he joined and it aggravated my son who was baffled that people kept hiring him anyway. I remarked on the fact that he got to put all those awesome projects on his resume and most people wouldn't realize he killed it.
He facepalmed.
My sister and I both were STAR Student (highest SAT score of our graduating high school class, plus top ten percent GPA) and won a National Merit Scholarship to UGA based on that. She accepted her scholarship. I declined mine.
If she cheated to get the SAT score and dummied up her grades, people hired her based on credentials that were fraudulent. But she had worked for the school paper and apparently was talented at working the system, not my strength.
In her twenties, she got accepted to a federal government training program on condition she agree to go wherever they sent her after she graduated. I've talked a little about that elsewhere.
Not mentioned: Her training was in a part of the country with coal burning power plants, this high levels of sulfur in the air, and she was diagnosed with Stevens-Johnson Syndrome, a potentially deadly allergic reaction.
Wikipedia says it has a 7.5 percent mortality rate. She told me it was thirty percent. Previous reading has suggested that's a figure for a more severe form of it. This would have been a lot of years ago and statistics like that and definitions of various conditions are a moving target.
Suffice it to say you can die from it. It's a very serious condition.
So she was deathly ill while in school, then started her first federal job immediately afterwards.
She's older than me. It may have been fifteen or twenty years later when I attended GIS in my thirties while very sick. I reacted allergically to sulfur in the air and was put on something like eight or nine prescription drugs so I could finish the course, failed to get the Internship with a National Laboratory to which I had applied and spent the following twenty-two months going through drug withdrawal and making an ass of myself in online forums.
So perhaps she didn't get career success because she's amazingly healthy and has a perfect attendance record and all the other BS she spouted for years. Maybe there's some OTHER explanation and maybe she cast herself in the role of The Ugly Sister to hide the truth and discourage suspicion.
Please note that people mistook us for each other for years and her own daughter reacted with initial bafflement at meeting "another mommy" and then grabbed a handful of hair from each of us to settle it in her mind. My sister has straight hair and I don't and her own baby decided that was the important difference between us.
No one was going "They are easy to tell apart. Doreen is pretty and her sister is ugly." She got called by my name by long-time family friends anytime she came to town while I still lived there and I got called by her name when I returned from Germany.
Other people couldn't readily distinguish us. This "pretty sister" meme was vastly overblown.
If you have a paid job with a security clearance and you put JOB XX date to YY date on your resume, future employers may have no meaningful ability to find out what you really did, much less ask if you slept your way into it. If they can verify that you actually had that job title for those dates, like the guy RUINING all the projects he joined, you may have a spiffy resume regardless of what really went on behind closed doors under a cloak of secrecy which most jobs involve regardless of the title. Corporations typically want you to keep your mouth shut, even if you just mop floors.
And if you are a wonderful supportive friend, you only get to keep those friendships if you keep your mouth shut and keep their secrets.
I spent some time with a defacto unpaid consultancy where people would give others my email address and say "Talk to her about your difficult kid!" And I would help people all the experts failed and they felt no obligation to pay me because we were "friends" though no one cared about my welfare.
I never figured out how to turn that into a paying business. I have no means to put that on a resume and claim credit for helping people with problems a lot of expensive professionals failed to adequately resolve. Trying to do so would likely get me viewed as a con artist and it's the kinds of problems people don't want to admit to, so good luck getting testimonials with which to grow a business.
I was a homemaker for a lot of years. I did good things for people and they treated it like it was free because I cared and when I got divorced, no one cared about me and no one helped me turn all those years of service and problem solving into an income.
And still expect me to keep their secrets and not blab them on the Internet as "entertainment" in hopes of making a buck.
