Kelly Process Engineer interview questions

Headhunter approached me with the job. Was pretty polite with the approach but as as we talk into more detail the headhunter got very flakey and not as responsive as she should've been. While asking her for more details about the job, she just repeatedly sending the same info. When asking about the compensation range, she became angry and spending 5 minutes educating me how the recruiting industry does not give out any info. Extremely unprofessional. Do not recommend dealing with.
