What is the difference between consulting targets and IB targets?

There isn’t really a difference/ undergrads severely overstate it. The truth is there are highly ranked academic institutions and ones that are less highly ranked. If you at a top 10 school, more students might go to IB versus consulting or vice versa, but both are going to likely have solid recruiting pipelines/ opportunities. Generally people will say things are targets more one way than another because specific firms consistently get individuals from certain academic institutions. For example, my bank always would have like 4-5 slots they reserved for kids from my school. That said, it is considered more of a consulting target because many go into consulting from the school. 
 

I don’t know why you care/ whether you are in hs or are stressing about your ability to get a job coming from a certain school, but I really wouldn’t worry about it. A student that goes to a school that has less of a rep at a firm will still get a solid shot if other parts of their resume is up to par.
