I applied online and received an invitation from National Instruments to interview onsite. The interview was about an hour long. The first part of the interview (~35 min) consisted of behavioral interview questions. There were three interviewers in the room (all technical writers and all very pleasant) who asked the typical behavioral questions, as well as questions regarding my past experiences and questions that asked what I knew about NI and its culture/values. The second part of the interview (strict 20 min) consisted of an editing test that had me mark up four or five pages of one of NI's product manuals for things such as clarity, grammar, and consistency in numbering, titles, fonts, etc. You didn't have to use specific proofreading marks as long as you got your point across. While I felt rushed to complete the editing test, the overall interview was relaxed and not very stressful, assuming you've practiced your behavioral interviewing and have some answers handy. After about two weeks, I received an email notifying me that I was selected for a full-day interview (note: the first interview described above would probably be replaced by a phone interview sans editing test for those not already living in Austin, like I was). The campus interview lasted from 10am-3pm, and included a campus tour, an informal lunch with other writers, and a friendly host that took you through the whole process. There were two or three 45-60 min interviews that followed the same format as my first interview: three interviewers asking behavioral questions and relating your answers to your past experiences and to the culture at NI. The only difference was that near the end of those interview sessions, the interviewers might talk to you about career paths or other 'Why NI?' topics and/or open up the remaining time for you to ask them questions. I also interviewed with an engineer in the form of an off the cuff discussion about a technology he was working on, although we actually went off on a tangent that became very informal (just note you will be asked to describe the technology the engineer introduced you to in the afternoon interview session). Sometime after lunch I had to take another 20 min editing test, although this time I was made to write a conceptual topic and a procedural topic on a computer (not sure if people who haven't taken the written test will have to do this). I used Notepad to complete the exercise, and my end product was a list with an introductory sentence and a few steps and substeps, as well as a short paragraph describing a small application I was told to play around with. To conclude the day, you interview with a manager or HR representative that discusses NI's benefits and culture in more detail, and this is really an information session and not an interview. Again, the overall interview process was pleasant as everyone was friendly and since NI's culture very laid-back and open. I received notification of the job offer just before the two-week mark.
