It was supposedly a formal interview but seemed rather informal based on the atmosphere of the office and the amount of time I had to wait. It was ultimately easy to make a decision to not continue with the process based on the initial interview.

This company is a scam don't lose your time going to an interview at their office. They asked to come for an interview just 1 day after I applied on Linkedin. I was received by the "CEO" of Marketing on 6th (they also operate under the name Robinson Brandt International with another CEO). The guy looked very professional and was asking classic interview questions but wasn't clear at all about the assignements and the remuneration (I'm not a native english speaker and I think he was forcing his Irish accent for me not to understand him very well). After this quick interview I was contacted by phone to do another one the next day but after reading the other glassdoor reviews I realized it was a scam. I have noticed that they post job offers everyday (for different positions which are actually all the same) which only testify how many people try to work for them and leave after a few days.
