National Instruments interview questions

One OA followed by two technical round. OA has two problems - medium to hard difficulty. 1st technical round has two problems: Easy to medium. 2nd technical was managerial round. It was more on technical side (project related discussions were made).

1 hour long technical/behavioral interview on campus then 2 30 minute 'interviews' with sales managers over personality and fit for the role. The process was very easy and HR was always very accommodating and made sure to keep me updated on the process. It took about 4 weeks in total to get the offer.
