Upstream Director interview questions

They took me through months of interviewing talking to over 9 people and some of these people multiple times wasting a lot of time on the phone and in person. I even had to take half week off for an onsite interview flying to Europe. Eventually, the offered me the position but managed to keep dragging on the process and lying quite frequently along the process. What a waste of time and energy Very unprofessional and unethical company.
