I applied online. The process took 2 weeks. I interviewed at Groupon in Mar 2012
Interview
The interview was more like Q&A session. The company man described the job he expected from intern because I didn't have any background in the industry (selling deals). He also told me the working period he required for summer internship but unfortunately my available time was not enough. He wanted 4 months but I only have 3.
I applied in-person. The process took 3 days. I interviewed at Groupon (Petaling Jaya) in May 2015
Interview
Once I reached, I was call into a room with another girl who is also interviewing for internship. It was easy and straight forward, don't need to be stress, be yourself.
