Candidate interview experiences
First-hand accounts from people who interviewed at Rockwell Collins.
Development Engineer
The interview was online with multiple participants. Oddly, only 3 out of 4 introduced themselves, and a 5th person joined later, just listening. This made it unclear who everyone was and how deep to go with answers, given the uncertainty about their background knowledge. The conversation just kind of drifted along. We did the usual intros, which felt unnecessary given the info already on the website and profiles. When we asked questions, the answers were often 'not important right now' or 'confidential.' The discussion did touch on helicopters, the technology, and possible tasks, but it wasn't clear what exactly they were looking for, or who they were trying to find. It felt like they were just broadly assessing candidates and would sort them out later, lacking a clear strategy for who they needed. On a personal level, two interviewers were pleasant, as expected, but two others seemed disengaged, with at least one clearly multitasking. It didn't really convey a strong interest in the candidate.
- Could you explain your academic choices and why you pursued your specific field of study?
- What motivated you to apply for this particular role?
- Based on your understanding, what makes you a strong candidate for this position?
Software Engineer
First up was a round on embedded systems basics, covering C, DO178B, avionics, and RTOS. Then, a technical interview with the tech lead, followed by a managerial chat. After that, it was the HR round.
- Tell me about C++ Embedded C.
- What are the basics of C?
- Can you explain DO178B?
Software Engineer
There were 2 technical rounds and 1 manager round. The technical rounds were face-to-face, and the manager round could be over the phone or face-to-face. The first technical round covered basic concepts related to requirements and software processes if you're from a similar background. The second technical round involved logical and puzzle-based questions. There was also a background check and an offer stage.
- Were pure technical and domain knowledge questions asked?
- Were some logical questions, like how do you solve tricky questions, asked?
- Were some questions related to your previous experience asked?
