test the interview. check the interview what is the test and what is the When an interviewer asks, “Do you have any questions?” for a Software Engineer III (mid–senior level) role, this is not optional—it’s part of how they evaluate you. At this level, your questions should show ownership, system thinking, and impact, not just curiosity.

1. Online Coding Round Platform: Hackerrank / Codility / Company Portal Duration: 60–90 minutes Format: 2–3 coding problems (Data Structures + Logic) Languages allowed: C/C++/Python Topics: Arrays & Strings Bit Manipulation Pointers in C Recursion / Linked List OS-based MCQs (Scheduling, Memory Management) Sample Questions: Reverse a linked list Implement strcpy without using library Count set bits in a number Implement round-robin scheduling logic ✅ 2. Technical Interview – Round 1 Mode: Virtual / Telephonic Focus: Core Programming + OS + Embedded Knowledge Topics Covered: C/C++ concepts (pointers, memory management, arrays) OS concepts (processes, threads, synchronization) DSA: Linked lists, stacks, queues Basics of device drivers or embedded C (if you mentioned projects) Tip: They may ask you to write code or analyze it on a shared screen or in C syntax. ✅ 3. Technical Interview – Round 2 (System Design + Projects) Mode: Virtual / In-person Focus: Project Deep Dive + Real-World Systems Thinking Discuss any projects related to: Embedded Systems / Firmware IoT or Dashboard UIs System-level design (e.g., memory handling, OS internals) May ask you to: Design a simple IoT system Explain how memory is managed in your project Handle inter-process communication ✅ 4. HR / Behavioral Round Mode: Phone/Video Call Questions May Include: Tell me about yourself. Why Semtech? Strengths & weaknesses. Situational questions (working in a team, conflict resolution). ✨ How to Stand Out Mention any work with microcontrollers, sensors, Arduino, or Raspberry Pi. Show hands-on experience with C/C++ and memory-level programming. Projects using React UI for hardware dashboards are a bonus. Emphasize your interest in low-level and systems programming.
