Collins Aerospace interview questions

Easy interview process. Hiring manager was very nice, and made it clear that he would only use the input from his team to make a final decision, not from himself. Fully remote

What a waste of time: 5 hours interview process (plus presentation preparation) for 2 positions (I had applied for 1 only). 1 hour presentation, technical questions (3 hours) and non technical questions from Director and HR (1 hour). In the end, they do not seem to be really hiring (which is why their positions have been advertised for months). And the worst thing is that after a 5 hours interview, I got an automated email from Raytheon at 8pm in the evening (with no feedback at all) that said 'we are not proceeding'. They are ridiculous.
