I applied through college or university. The process took 2 days. I interviewed at Commvault in Aug 2019
Interview
First-round was coding round. There were 1 demo question and 5 real coding questions. They provided only c++ and java as programming languages for coding and you were not allowed to use inbuilt libraries like <algorithm>. These are 4 out of 5 questions
Interview questions [1]
Question 1
Q.1 Left view of binary tree
Q.2 Copy the content of a 2d array into a new 2d array but allocate the size of the new array dynamically by using the ‘new’ operator in c++.
Q.3 You are given a number n. Find the total no. of binary numbers that can be represented in n digits and having two consecutive 1’s.
Example: – n=3 binary no. in 3 digits can be 000, 001, 010, 100, 101, 110, 111 but only 110 and 111 has two consecutive 1’s so answer will be 2.
Q.4 Remove the duplicate nodes from a singly LinkedList.

Interview
Initial screening with three coding questions.
Second round was a lengthy coding session where we are expected to solve low level design kind of questions. This can usually take hours to solve. There will be an interviewer with you for the entire duration.
Third round would have some technical questions and some behavioural questions.

Question 1
Variation of LCS, Solution was straight forward after identifying this.
I applied online. The process took 4 weeks. I interviewed at Commvault (Seoul) in Feb 2025
Interview
Clumio team. Moderate(medium ~ easy hard of leetcode) coding questions and little system design. Interviewers were kind and mostly it was discussion about the problem. Best interview experience I had in korea.
I applied online. The process took 3 weeks. I interviewed at Commvault (Seoul) in Jan 2025
Interview
1 online test => concurreny, CS
2 coding test => leetcode but more low level system design
2 coding test => leetcode + resume question + behavior question
The coding interview problem is quite difficult in the korea
but the quailty of problems are really good
