Interviewed Sep 2011 in Austin, TX (took 1+ week)
The interviewer is a really nice lady. She first asked me about my projects appeared in my resume. We have talked some technical problems arised by each other. Then she asked me to solve a problem based on binary tree in both recursion and iterative ways. It is not hard. Then she asked me about the most intereting bug I have ever met. Then it is finished . One hour long.

Starts with a written test comprising of code snippets and computer puzzles. After one clears the written round one needs to go through 2-3 face to face interview rounds. Each is rejection based. Say, in case you don't get through round 1 then you would be asked to leave.

Interviewed Apr 2011 in Austin, TX (took a day)
I applied online, around 2 or 3 weeks later I got an email from NI for a phone interview. I got the email in the morning and we scheduled the interview for that same afternoon. A senior engineer asked me some work status, behavioral, and technical questions. It was 55 minutes long.
After I got the email I appeared in the National Instruments system as “Under consideration”. Next morning, after my phone interview, my status was ” Not Selected”. I didn’t hear from them again. I believed I answered well 1.5 out of the 3 main technical questions.
Interview Questions
- Talk about the worst bug you have had.
- Which language do you prefer (They don’t really use Java, mostly C++/C#)
Technical Questions:
-If you are designed an mp3, how will you shuffle a music list? Suppose the list is 10 songs? Suppose now the list is 10.000 songs?
-If you are designing and text editor from zero, what data structure will you use to save the text? How will you manage the memory?
-If you have a binary tree, how will you calculate the average of all the nodes in the tree? The binary tree can have many nodes. Write a code that will give average of the sum in binary tree.

Interviewed Mar 2011 (took a day)
I had already worked for the company before as an intern, so I was called back for an on-site interview. It was a full day process: started at 8 and ended at about 5. Three interviews of 1 hr 15 mins each from three different groups depending on what your abilities are. Usually this consists of a manager, who asks leadership/behavioral questions based on the resume, and a technical person from a group, who asks more tech based questions.
