Banff Constructors interview questions

This started with a phone call in June. Then a second phone call a few days later. Then we scheduled an in person interview in July. An entire month and a half after the phone call. After the interview, I maintained regular contact with them, asking where they were at, if they needed more from me. They always responded. Until they didn’t. They strung me along for 2 months. 2 entire months. Didn’t have the decency to reject me, or inform me about what was going on. Highly unprofessional, extremely rude.
