The event is called Yahoo! Day, in which almost all candidates are new grads.

There were three one-hour technical interviews. The interviewers were all very polite and nice.

However, in my case, Yahoo's recruiters were not professional at all. After the onsite interview, I sent them 5 emails to follow up but got zero reply.

It has been almost 2 months now.

Assume you are designing a CocoaPod package managing system. Try to illustrate how you would resolve package dependencies.

Given a set of true statements, for example:

• A = B
• A = C
• C = E

And a set of false statements, like:

• A != C
• B != E

Test if the overall result is true.
