I was abroad in the fall, during all the big interviews for a summer internship. Believe me, that was a risk, although I used it to my advantage. You know when recruiters come to your school and you don't know what to say, but you still want to introduce yourself? In the spring recruitment events before the fall interview season, I made sure to tell the recruiter that I'm interested in the internship, but I'm hoping that my time abroad wouldn't negatively impact my ability to apply. Pretty much every time I asked (any of the big 4) they told me I could still apply, and they would either interview me abroad, even offered for me to come to the office on an individual tour and early interview in the summer because they didn't think going abroad should be a reason to disqualify me. They always gave me their email and instead of saying "feel free to keep in touch," I was told "shoot me an email and remind me about your internship. I'll make sure you can still interview, that shouldn't be a problem." And instantly, you have something for them to remember you by, and a problem to work on that will lead to multiple exchanges.
I had two interviews via skype for business, and each was a half hour, but at 1:00 am where I was. Both of my interviewers were extremely relaxed, each began with a quick question about how my abroad session is going or what time it is for me, then they told me about the company and their own journey with the company, and then asked me two "real" questions, and if I had any questions for them.
Of all the firms I interviewed with, I thought this was the most conversational, the most considerate in easing into the interview questions naturally, and I learned the most about my interviewers.
