Antra Frontend Developer interview questions

They old me about company and benefits rhey provide And if I go I will have to pay $1000 per month Then I was asked about myself and solved some challenges like math operations

I spent the a month working on making projects for my portfolio, mastering common interview questions, attending programming meetups and it's Very quick interview process. 1st Recruiter, 2nd technical and then offer was given. Extremely easy interview and very skeptical offer was given.
