I applied online. The process took 2+ months. I interviewed at Kakao (Seoul) in May 2019
Interview
The first two processes were coding tests and the third was a video call. The questions were based on the problems of the coding test taken previously. The interview was 1:2.
Interview questions [1]
Question 1
Explain the question and solution of the previous coding test mathematically.
Terrible.
For foreigners it is impossible to get in kakao because they focus on language skills more than technical skills.
I passed the online test and all the technical rounds but they rejected me after the HR interview.
