There's loads of people on Twitter who will follow you back if you follow them - trick is to do a member search for a related term, look for people who have a similar amount of followers as people they're following (this shows they tend to follow back) and follow them. You'll hit a follow limit at 2000 but that should give you a decent start at least.
If you don't want the job people to suss this is what you've done wait until just before the interview and unfollow everyone....
