National Instruments Software Engineer I interview questions

I got the interview on campus, The recuriter is very nice, during the interview, he asked some behavior questions and very standard data structure question about tree, no design question.

There were three rounds in total. The first round was a written test which was a mix of aptitude, Computer Science and a few Electronics questions. The second round was a coding round which had two programs. The first one was to find the number of anagrams in a sentence. The second one was a variation of four in a row game- find the winner. The interview questions were based on the coding round programs- optimize the solution etc. The other question was to write code for evaluating an expression tree.
