I applied online. The process took 2 months. I interviewed at Samsung Electronics (Seoul) in Apr 2014
Interview
online application, followed by written test. the written test was somehow IQ test with numerical test, all the contents was written in Korean. there are many reference book for the test available in the bookstore, so it is better to pracice before you take the exam.
