National Instruments Engineering Leadership Programmer interview questions

I applied online and after a week I got a schedule for a telephone interview. Mostly behavioural questions and what do I know about the company and its products. Then it was an online technical test which consisted of 47 questions to answer in 50 minutes, mechanical, electronics mostly. After two days I received an invitation to the assessment center, where it consisted of behavioural and technical interview, a group exercise and a presentation.
