Customised technologies interview date

Where can we ask to shift interview date?
Usually weekends r allotted for interview but for this company it is this Monday

I don’t think that it is possible to shift the date on our convenience. I suggest you attend it.

Do you know how many days it will take the process?
Since I would be coming from outer station if they say they will announce results of written test after a gap of few days, then there is no purpose of me visiting the company.

Not everyone is free on weekdays… I hope they kindly consider…
