It depends on what your end goals are. If you are going at it alone, this, or any other service should suffice. If you are also thinking of implementing a custom process and your company will have "secret sauce", you are probably better off developing your own solution.

A few points to consider:
* You want to make sure the product you use is reliable and safe. You will be storing PII for your candidates, the app has to do a good job protecting PII
* From what I can tell, you still need to deploy this app yourself. If you don't have technical expertise, I wouldn't recommend it. You would be responsible for its reliability scalability, and security which is not trivial. An alternative is to use a SaaS product, which comes with all of the above managed by the provider
