These are not good reasons and again shows that the company really doesn't care. IT gives a bad laptop? That's fine it doesn't have to be good, it just needs a text editor open. Get a USB drive with a linux distro and boot to it and open nano. Or bring your laptop and stick the USB drive linux distro in there and let them use it. Again there is zero excuse for a company to not have a laptop ready for an onsite interview.

All these companies expect you to write code using a site like hackerrank during the phone screen. And yet they can't have a chromebook open to the exact same site during the onsite? If that's too much, they can't even get a cheap laptop, stick in a USB drive linux distro, open nano and give that during the onsite?
