The problem is that big companies (Google, Oracle, Facebook, and others) are doing the same tricks: good engineers can work on very interesting projects, equity potential is great (10% of stock price increase will get you significant chunk of money), the best people in the field will be your co-workers, etc.
On the other hand, startups will not train on job (or allow you to explore new things), will not allow working remote, etc. Plus, as per suggestion, you need to ask candidates to do 'trial projects' (which probably tells candidate that you are hiring low-level CRUD programers), you will not be able to match salary, etc.
I guess the only way to recruit top-talent is present that your company is doing something important and novel - and for engineers that bar is quite high.
