Candidate Tests - any recommended vendors?

Summary

We are looking to evaluate our candidates through tests using a third party vendor - any suggestions?

Hello

We have a requirement in our firm to offer candidate tests - these tests are used in some of our Eastern European offices, as many of our other offices globally, don't and won't use these form of assessments during the recruitment process.

My questions are:

1  does anyone use a 'test' - this will include several multiple choice type questions with one or two text based questions

2 we need to be able to use our own set of questions, not any provided by a third party vendor
