Travelzoo Producer interview questions

I had a such rude interview process with the recruiter from this company. I applied the position for Producer where is based in Singapore.The Recruiter from Hong Kong messaged me for the first interview. But in the end, she cancelled my interview for 3 times. At first, we set the date for interview on Saturday evening, so I was preparing for whole day, but I received message from the recruiter that could not make it after 20min scheduled time. I was surprised, but I thought it's ok, and rescheduled to lunch time in other day. But again, before 5 min of the interview time, she told me that she could not make it. Then the person told me to have interview at 8pm after 2 days for sure. I was upset already but I accepted it, Because still I was interested in the position. In that day, I was waiting for the interview and I have texted her by Skype but after 20min passed, she just messaged me, "sorry I forgot, went out for dinner" I have no words.. and I just realized that she was not interested in having interview with me. I was very disappointed about whole interview process and found it was very unprofessional. My first interview never happened. But after 3 times cancellation, I won't take it anyway.
