I used a mac for it last year and it worked fine
Why would it make a difference if you are using Safari? It technically should be compatible with other browsers. It doesn't make technology sense to me, which is why I am asking... and I have a Mac, so wondering if I should find a PC to use for this?
I was rejected after the Web-based interview too, and I was really distraught about it (especially since I had already successfully participated in the program back in fall 2006). The next day, I couldn't see any reason why I shouldn't be considered, so I called them. As it turned out, I took my WBI on a Mac. However, the Web Based Interview portion MUST be taken on Internet Explorer! The wonderful hiring manager reset the interview and I passed the second time around. Make sure that you're using Internet Explorer when you take the WBI, otherwise it will give them bad results. The second time around, I was accepted!
I know! It was such a bad mistake to require IE. No Macs use that anymore!
Although it's really outdated and unsupported by microsoft, you can still install an old version of IE on a Mac. That's what I did for the CP application, and it worked fine. Google it and you'll find several places to download it.
I would really try to use IE if you can. I can tell you they're not kidding about needing IE. I accidently did my acceptance in Firefox and it got all messed up, I had to have Tech Support help me so I could pay my fee. I had done the WBI on campus right after I did the information session, so the recruiter's stressing IE was still in my head.
There are some forms (and banks) that will only work with IE, it has to do with the coding. Trust me, I hate IE as much as most people (probably more, I've been a Firefox girl for YEARS) but in this instance, you've got to suck it up. It's not worth something getting screwed up just because you're stubborn about using a different browser
