The site is not mobile friendly. It works but looks funny on a phone.
If you request the desktop page it looks fine on my phone.
However, I think a lot of people do expect a responsive website that adjusts for mobile viewing. Also, many people may not even be aware they can request a desktop page. So for some people who are viewing in their mobile, the page feels unprofessional.
It would not be too much work to add some jquery or otherwise conditionally change the gui to change size and placement to look good on a mobile. This would help make the sites appear more legitimate. Its wordpress so a change in theme could work, but more importantly, it works.
In my opinion, I hope the concentration is in the backend and AI itself. Making the site responsive for mobile should be done sure, but base functionality is more crucial.
So give the programmers a break on the gui and realize they hopefully were more concerned about security and main goal of the functions required. I hope before changing the ui for mobile they add some security like 2 stage authentication.
