Always double check if the site/mail/person is the real one.
Not even being able to find any of the team online is what amuses me. In fact, some of them go as far as opening a fake LinkedIn profile with one huge fake position they have occupied over the years and some fake pictures, and the account was opened just few weeks back. Seriously ? I cannot remember the exact project, but these guys lied about the team and office address and luckily one of the community members who lives around here ended up finding out. That is the extent at which some of them ends up going, which is why my main target has always been the team, and once I am okay with that, I can start asking other relevant questions.
