They don't seem to be too suspicious but hey, it doesn't mean they don't make mistakes. They state that the best way to reach them is through someone in their network, so that's why you should email them. At the same time, they provide no alternative contacts. Moreover, what's surprised me the most is that the team introduction is so lame. You know, looking at their website you can't say that there's something wrong, it's seen they spent money on the design and made some efforts to do something right. At least. Their social media profiles are active, so it means the company is alive. But making mistakes like this are just stupid! I never expected them to do this...
