TRIMANE interview questions

I saw a post on LinkedIn then I commented to show my interest. I was then contacted through LinkedIn messaging, then a phone call. An interview was then confirmed through email. I had the interview late in the evening, as an arrangement because I was working somewhere else. I think they are a bit rude because I never got a response, despite sending back some emails. A friend of mine was also complaining about the same thing. I guess they have to improve on that.
