Not difficult. A lot of behavioral questions about a time you had a conflict with someone and how you went to solve it, why you think you are a good fit for this company.
Mainly behavioral questions: why Collins, hardest engineering challenge, how you approach work, etc. The team took about 1-2 months to get back to me with an offer. There were no technical questions.
