Software Engineer Interview

Software Engineer
New York, NY

I applied through college or university and the process took a day - interviewed at CommVault in February 2014.

Interview Details – It was the first technical interview, and I and bunch of people had to solve some programming questions in a big room. We had 90 minutes to solve 3 algorithm questions. The questions are not that easy or not that hard. But you can use internet freely during the test.

Interview Question – The questions were related to data structure problems such as linked list, tree, etc. You code in a web browser, and it's tricky. It is basically just like using a memo pad.   Answer Question

Software Engineer Interview

Software Engineer
Gainesville, FL

I applied through college or university and the process took 2 weeks - interviewed at CommVault in October 2013.

Interview Details – Commvault had visited our campus for the career fair. Some of us got a mail the same night to attend a programming challenge the next day at the University.
There were three programs with 5,6,7 marks. They instructed us to solve any one first and then attempt the others.
Question were : Convert a number to binary, Find if a loop exists in a Linked List. Can't recall the third one.
It was a online compiler type interview. So you had to write, compile execute and pass their tests.

I then got a mail for a telephonic. The guy asked me just one question.
char *a="something";
Is this valid or invalid. Give reasons.
Then what would
strlen(a) return?

The next question was what is sizeof.

That's it. Simple basic stuff.

Interview Question – char *a="something"; Valid / Invalid.   View Answer

Software Engineer Interview

Software Engineer
Hyderābād (India)

I applied through a staffing agency and the process took 1+ week - interviewed at CommVault in June 2010.

Interview Details – The first part of the interview was a lengthy written test which I have to give even with 5 years of Development experience. Many of my friends wan't able to clear the written test, but I cleared it.

The next portion is debugging test where you have to go to there office, and debug a program in 3 hours and fix it. Initially it will not even be at compilation stage.

I went through the whole process but the main bug I didn't fixed. And I made a fix at wrong place, so the bug is gone and was not reproducible. Even the person who was observing my system, got confused.

Later on he did a stress test on the system, and then the bug was reproduced but I ran out of time.

Interview Question – debug a program   View Answer
