I applied online. The process took 3 weeks. I interviewed at KLA (Seoul) in Feb 2017
Interview
Submit Cover letter and Resume -> Got a phone call -> Phone interview in English -> Group interview in person -> Group Interview with director -> Got a confirmation email from KLA
Had a 4 hour in person interview with the local team. Every hour was a new round of people. Most questions were repeated per session. Overall, it was a positive experience.
During the interview I was asked some questions about my views on my career, my personal three and five year plans. I was also asked some questions based on English documents.
