I'm an embedded software engineer with 4 years of experience in the industry and 1 year of lead software experience. I applied for the Flight Engineer II role and after 2 weeks was sent a technical assessment to complete which I spent the weekend on. The next morning I received a generic "we will not proceed based on your submission" email which was surprising given the role only required 2 years of experience. I sent a follow up asking for some feedback and was told "there were no red flags or areas for improvement, they just thought your submission would be better given your experience". When I asked for some actionable feedback so I could improve my work in the future I received no reply.
