Revelock interview questions

Scouted via trycircular.com. After sending me the job description and an interview proposal they disappeared. They wrote me in Spanish despite I fill-up my profile stating that I'm just speaking english (non native speaker tho). After using google translate I got that they were asking my email address moving out the conversation from the trycircular.com portal. They showed as "very interested" in my profile. Not serious and superficial.
