National Instruments Software Engineering interview questions

The interview was conducted in the university. It was a 45-minute interview containing both technical and behavioral questions. They invited for a dinner the next day, which was an indication that the result was positive. I got a package (mail) with the offer letter in two weeks.

Written round Consisted of 10 questions of 90 minute duration consisting questions on C, FAFL, Algorithms, probability, permutaion and combination, microprocessors. Coding round 2 questions with 3 hr duration 1. Long question, I don't remember fully. I'll just give input/output examples. It was basically on string decoding. If jon2snow3 is there the decoded string will be jonjonsnowjonjonsnowjonjonsnow. Given a string and an integer k we have print the kth character in the decoded string input: jon2snow3   8 output:  n 2. Given an array and an integer k return the number of contiguous sub arrays whose sum is divisible by k. input format: n k <n elements of the array> input:  4 5 10 0 4 5 output:  4 explaination: {10},{0},{10,0},{5} are the sub arrays with sum divisible by 5.
