I applied through university. The process took 2 days. I interviewed at Commvault (North Twenty Four Parganas) in Aug 2020
Interview
The selection process comprised of a coding round, a power programming round, 2 technical interview rounds and a HR round.(Every round was an elimination round)
The first round comprised of 3 coding questions and 15 Mcqs related to basic oops concepts, DBMS and OS.
The second round was basically the difficult part. It was a continuous coding round for around 7 hours wherein we were given a basic structure of a file system and we had to design the file system as per the requirements of the question and in the starting hours we had to design the classes and if the design impressed the mentor then only we could do the further coding of the functions. The mentors were there to help us with our doubts regarding the question.And there was a progress check in almost every hour and students were asked to leave if the progress was not good enough.
Next round was the Technical Interview round where they focused on OOPS concepts, DBMS and OS.
I could reach up to the second round only.
Interview questions [4]
Question 1
Round1:There is a bag of different types of coins.There is an array where a[i] was the number of coins of type i. Find the minimum number of withdrawals needed to be done from the bag such that you have minimum of 5 coins of each type. Given that in every withdrawal you can pick only one coin and after picking up the coin only you know about the type of the coin.If it is not possible then return -1;
Round 2: Create a file system which has the following functions:
1. add a file(whose full path is given) along with the directories inside which it is present.
2. Append a file(Append the data of a file
3. Create a linked file(hard link)
4. Append linked file
5. delete link
6. move file from one directory to another
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
It was campus recruitment,
Round 1 was proctored exam with 2 sections. Section 1 was programming aptitude and section 2 was coding.
Initially we were given choice to select between language(JAVA and CPP). it was according to our chosen language the questions were there.

Question 1
The coding question were like including bit manipulation, question involving strings etc.
