Real, anonymous reports from people who interviewed for Software Engineer at Mitel Networks, newest first and distilled into what to expect across the loop.
Recruiter outreach came first, and then the process landed me into a fully technical setup over video. I remember the focus feeling very telecom-heavy: SIP came up a lot, alongside C and C++ discussion tied back to what I had done before. My experience mattered, not just in theory—there was a clear sense that the decision would be based on my background and how it matched what they needed.
My interview journey started with an online test, and the questions skewed toward fundamentals—basic OOP and core CS concepts. It was followed by a technical interview delivered virtually, where the whole session ran about 50 minutes. The technical round felt like a continuation of what the test measured: straightforward but still requiring solid recall and problem-solving.
