Trend Micro Inc. Senior Engineer - Developer interview questions

The interview process began with an Online Assessment consisting of three coding questions: two LeetCode medium-level problems (focused on Sorting and Heap) and one LeetCode hard-level problem (based on Dynamic Programming). After clearing the OA, there was an HR screening round that covered background verification and general fit-related discussions. The next stage was Technical Round 1 (virtual), which included in-depth questions about my resume, discussions related to the role, and some behavioral questions. Technical Round 2 was conducted onsite. This round included one DSA problem, a Low-Level Design (LLD) question, deep-dive questions on my resume, and behavioral questions as well.

2 technical interviewers, nice guys, go over your history for 5min. Then they asked me to draw a full system diagram (e.g. cloud) for a past job, and spent a solid 30 min critiquing it (security, scalability, purpose, alternatives). What if you did it with microservices (draw another diagram)? What about if you did it event-driven (e.g. SQS+EventBridge+Lambda)? Ended with asking about AI, specifics about why I did some things on my resume. No behavioral questions, no questions about my code test (I did fairly good on the code test already).
