"I cold applied for Sierra's APX role, which is basically an early-career rotational role mixing PM, coding, and some customer-facing work. The process for me was a short recruiter chat, then a 1-hour live technical with one debugging problem and one Python traversal problem, and then an in-person onsite with a more product-heavy debugging round plus a product design round with the head of product. Overall it felt much more hands-on and practical than a normal LeetCode process, especially because so much of it centered on debugging and understanding an unfamiliar codebase quickly. The onsite also made it clear they want APX people to switch between engineering and product thinking, because even the debugging questions turned into customer impact questions. I finished the loop last Thursday and I’m still waiting to hear back."

"The interview process was fairly structured, starting with an initial screening followed by technical and/or managerial rounds. What went well was the clarity of questions and the opportunity to explain my thought process. One area that could have been better was the time allocated for certain discussions, which felt slightly rushed."
