Instron Field Service Engineer interview questions

Unfortunate waste of time. 2 phone interviews, 7 in person interviews. Wasted 2 months of my time. Mind you, the job is STILL open from over 5 months. All the field service jobs are. Strong resume and background, heavy customer service. ONE person did not like me (out of 8, you do the math) and you are not given the job. The way of doing Google interviewing is over. Simply put, how in the world do a bunch of suits in corporate assess that a service engineer (that is in the field and they are not) would not do a good job. Boggles my mind. Would pass with Instron.
