I actually have not come to the interview because after some investigation I found this company a little shady. The reason why I found it unreliable to proceed is that while this is a scientific publishing firm, their job advertisement, website, and interview invitation email are written in a very unprofessional way. The company history doesn't show any activities for the recent 5-6 years until recently. Their name also changed from Food company (world food) to this publishing one, while not changing their email. The person calling me, at first, asked me to come to Helsinki for an interview on Saturday (I live in Tampere and he called on Friday noon). In short, I just felt not reliable enough to continue the process. Would like to hear more about others' experiences.
