I just got an offer from Mckinsey, is there a problem if my sister works at BCG?

No, that is not a problem (and the background check is not about that). 

You can keep your job (and your sister). You just can't talk with her about your work. More specifically, you can't talk to anyone about it, as confidentiality is key in this business.

Hi there,

First of all, congratulations on the offer!

This is indeed an interesting question which is probably relevant for quite a lot of users, so I am happy to provide my perspective on it:

• Generally speaking, this should not be an issue, especially since background checks are mostly resume-based. As such, as long as you did not display your whole family tree, there is almost no possibility to track your sister and her profession.
• Moreover, and you might have already seen this in your contract, you are required to maintain client confidentiality at all times and towards everybody outside of the company either way, not just towards employees of competitors.

In case you want a more detailed discussion on how to best prepare your upcoming career entry, please feel free to contact me directly.

I hope this helps,

Hi there,

Don't worry, you're perfectly safe! Of course, the same confidentiality rules that apply to everyone else you know also apply to her (i.e. don't talk details about your job).

Hello!

Congratulations and welcome!

No, it´s no problem at all. There are actually many couples in this situation (been there myself), which would be in principle much more complicated because you share the space at home!

And not even is there an issue, as long as you use your common sense. 

Hope it helps!

Cheers, 

Clara

None whatsoever provided both you and your sis maintain highest levels of professionalism & confidentiality of work and company assets.

What a bright family! No problem at all. All the best to you both!
