The most unorthodox "interview" I have ever attended and that is saying a lot considering the location and industry.
I was the only native English speaker present at the "group interview" , there were no interview questions. We had a pretend debate and nobody wanted to participate mostly because of lack of understanding of English and after all of my input and almost leading the group I was emailed saying my "attitude" was not what was expected.
This was all held in a hotel and afterwards I was the only person who wanted to see the contact center but we all ended up going to have a look. When we went there everyone looked like they were having a party rather than actually working. Typical really, don't go here if you want to actually work.
