It wasn't too bad...

My program experience was pretty good with Connect-123. The program lends itself to a lot of flexibility, depending on your preferences for what type of company or organization you would like to work. I appreciated that they went to great lengths to find an internship with an organization I liked and wanted to work for. I think the thing I was most unprepared for was living IN A CITY. Buenos Aires is HUGE. Coming from a background of suburbs and farmland, this was a huge shock to me and added to the stress of culture shock. I also was not prepared for the smoking. I had issues with people smoking in the house I was placed in, and Connect-123 was not very responsive to my complaints and requests to move housing. They said that I should have informed them of my severe second-hand smoke allergy. The one problem was this - ALL of the housing information I received from the program said their housing facilities are all non-smoking. If given this information, it seems logical to assume that I should not need to specify that I have a second-hand smoke allergy on my applications.
Apart from the smoking, the internship itself was great. I enjoyed working for the non-profit research organization where I was placed, including the people I worked with. The office was small, with only two other people working in my section, but I enjoyed the closeness with my coworkers and the ability to have open communication. However, I would say that I did get lucky in my placement. I spoke with a few other interns in B.A., and some of them were not happy with their placements because their bosses wished they had had a better/higher understanding of the Spanish language. Connect-123 says that it's okay to participate in their internships even if you don't know the native language of the country you're traveling to. Personally, I would recommend not looking in Buenos Aires if you're not in any way familiar with the Spanish language or only have an intermediate level. I was lucky enough to have a boss mostly fluent in English, but others on this program were not so lucky, and this definitely affected their overall experiences.
