Since the question refers to a developer (a special category of employees) the answer is a strong "Yes".

Absolutely. I'm a developer who has hired 15-20 other developers in my time. "talks to himself" isn't a reason not to hire a nice, talented developer.

"Alert! Phishing attempt!" would be my first thought on reading the second URL.

I would click on the first one, though.

You would because you are Greek and understand it. But what if it was Cyrillic or Chinese instead?

A domain in non-english characters communicates that the site has a high chance of being written in a non-english language.

Since I do not understand neither Cyrillic nor Chinese, I would probably not click on any of them.

Except:

1)...If I would really need to click on them (i.e. import some goods from China) in which case I would click on link and visit the site hoping that there is some kind of english description.

2)If I saw the link on Google (i.e. a search engine that I trust) and saw in the excerpt that there is some sort of legitimate description, it would be more likely that I would follow the link.
