Interbrand Designer interview questions

Submitted a resume and a portfolio to their website and got an email 2~3 days after. The interview took about 30 mins. There was no phone interview. Mostly talked about my work and the company background.

My interview experience with them was very stressful in the end. The HR staff contacted me after I applied online and had an interview with a couple of senior designers. The interview was ordinary, going through my portfolio and discussing about their projects and branding design etc. Until this moment, it was quick. The HR staff said they would let me notice the result for 2nd interview as soon as possible, but they didn't. After 2 weeks I followed up them by email and the HR staff said 'please wait more 2–3 weeks as they have some other candidates.' Then I waited, and didn't hear anything from them. I checked the HR again by phone after one and half a month since from the interview but she told me the same thing—that I have to wait more weeks. Even she didn't apologize about that. They haven't contacted me until now and I stop waiting for them and don't care about it. This interview experience is the worst and rudest thing I've ever faced.
