Diwa Learning Systems interview questions

The interview felt very unprofessional. In their job posting, they only specified that the required days to work is only from Monday to Friday, but in the very interview, I was asked if I would be able to work in the weekends. As I told them no, they told me that if I don't work for the weekends then it'll be considered as an absent. They should've indicated in their job posting that they would require you to work in the weekends if that's what the job really demands.

Interviewed by the HR first after the IQ exam then I was scheduled for technical exam about testing and then we proceed to technical interview and assessment of the technical exam.
