Yet another good interview test

time to read 1 min | 140 words

Yes, this is another challenge that I ran into which I consider well suited for an interview.

  • It is short
  • It doesn't require specific knowledge
  • There are a lot of ways of solving that
  • I can give the develop access to Google and the test is still valid

The test itself is very simple:

  • Detect if another instance of the application is running on the network which is registered to the same user
  • It doesn't have to be hack proof, and it doesn't have to be 100% complete. The purpose it to stop casual copying, not serious hackers.
    • A great example of the feature in action is R# detecting that two users are using the same license at the same time.

Oh, and for real world scenarios, use a licensing framework instead of rolling your own.
