There aren't many who do Career Start. I did CS two years ago & there were maybe 100 or so of us in total.
Once you get down to Disney, Career Start isn't really separated from the College Program. Both groups do the same roles & get paid the same amount. I had managers that when they went to do my check-in meetings, they didn't know that I was Career Start, they thought I was a regular CP.
If you're looking for people with your arrival date, I suggest searching on Facebook, not only for the Career Start groups, but also the College Program groups.
