National Instruments Hardware Engineer interview questions

Got an on Campus Interview on next day of the career fair. Interview was 45 min. HR question, Project Discussion, Technical Questions, Behavioral Questions and at the end gave chance to me if I have some questions for them. Have on-site interview next week.

On campus career fair. Interview was on the next day. And a couple of behavioural questions as well. Eg: describing about a project, what was the role, major problem and how was it tackled, etc.. Not very tough. Could have been better if properly prepared or gone through the concepts. It was a 45-minute interview, first 10 minutes behavioural, 30 minutes technical - 3 questions and they see the way you proceed in solving them (1. Some circuit was given and asked to draw the frequency response and find the cut off frequency 2. Design a circuit with a gain of 10) Do not remember the third question. Last 5 minutes - any questions to be asked. Didn't hear back after the interview.
