Travel therapy positions often have shorter interviews. The hiring site may be desperately looking to fill a position. As a therapist, you should still ask the right questions to get a feel for the work climate at the potential site.
Inquire about the job's productivity requirements, and ensure that you aren't taking on a demand that is outside of your comfort level. It can be helpful to ask, "How many patients will I be treating in an average day? Of this, what is the typical ratio of evaluations vs treatments"? You may have an expectation for the types of patients and conditions you will be encountering, but it is always worth asking to be sure. Job listings are not always accurate in their descriptions.
You can explicitly ask the interviewer to describe the culture of the facility, and what sets it apart from other companies. Another way to approach this would be to ask about permanent staff at the location, and how long they have been there. If you are new to the setting or a newer grad, you can also ask if the facility has the ability to provide guidance or a lower caseload initially as you get more comfortable.
The employer may have housing leads or suggestions that your travel company is unaware of. Be sure to do your own research as well, but if nothing is available on Furnished Finder, Airbnb, etc they may be able to provide helpful insight.
