I have been on both sides of the fence when it comes to recruitment. The one thing I learnt as a candidate is that recruiters can miss the mark when it comes to consistent communication and exceeding the needs of the candidate. 

Jumping from the candidate world to the recruiter world, I understand that it is important to keep up communication with candidates, even if it is just to see how they're doing.

There are always areas other than landing that job that candidates do care about and this is where you can find out.
