SaniSure interview questions

I interviewed through a agency. The initial interview the director was walking with me talking me up good like i had the position sealed and strung me on for four weeks having me do 4 interviews in 1 week and 6 total all not offer me and say they went with another person. Completely ridiculous. I am more than qualified for the job and they suddenly had chose another candidate. I spoke to the CEO , VP, and the COO in France . Took me to the final round just to say no, my worst experience ever. The people there had no idea what they were doing i walked in the building and nothing made sense. Terrible company
