Phone interview, then on site, 2 tests, and finally a little psychological analysis.
The interview process is one of the more involved that I have been through. Micro-Coax is thorough in their questions to be sure that you understand the science and material knowledge of the role you are applying for.
The psychological analysis is to make sure you are not a complete nut...a little crazy is acceptable. But really they just want to see what drives you, are you a go getter, a go with flow, or un-motivated. It is an interesting process to say the least but just stick with it.
