Collins Aerospace interview questions

I was shortlisted in campus placement. And the test had aptitude and techinical questions. Technical questions were related to mechanical and was hard. They shortlisted based on resume only 21 mechanical students were shortlisted. And then the test was medium difficult .

Straight forward phone call interview. Took less than 30 mins. The interviewer was friendly and described what the job is like. Also answered my questions in-depth and clearly. Would recommend
